These filters mount on the inside of the aquarium, rather than hanging from the outside -- making it possible to place the tank flush against a wall. In-Tank Filters are unusually quiet, since the motor is under the water. Offering the same quality and performance as an external filter, the Whisper In-Tank Filter will function in as little as 2 inches of water -- making it ideal for turtle tanks, or for creating a waterfall inside the tank.The Whisper In-Tank filter features adjusts easily to high or low water levels with mounting suction cups and/or bracket. Each filter comes with one pre-assembled Whisper Bio-Bag filter cartridge.

User questions & answers

Question:	Does this come with a filter cartridge
Answer:	Comes with the filter cartridge and bio-scrubber which works much better than previous models. I'm very happy with this filter. Have 2 turtles (that are very dirty) and it keeps my water crystal clear.
Question:	Would a small fish get sucked up in this filter? I have a 2 month old beta who is just recently getting color fins but still very small
Answer:	it would. Because the fish has to sleep. Unless you have a bigger tank, it will be sucked in when they fell asleep even if she is strong to swim away while awake. I would cover the water intake with filter mesh or unwanted nylon silk stockings
Question:	Where can I just get the Bioscrubber
Answer:	Hello. You can get it at a pet store, amazon has some, grocery stores with a pet section...they are pretty easy to find.
Question:	What size replacement filter cartridge for this unit...small, med
Answer:	The Tetra Bio-Bag Large (formerly known as Regular) are the exact same as the filter bag supplied with the Tetra Whisper In-Tank filter 20i. I got both from Amazon: filter $11.89; 12 cartridges $12.28. These filters last a long time, can be cleaned and reused. For my purpose, this filter has been great.

User questions & answers

Question:	can I order the media basket the filters are placed in
Answer:	yes I believe you can order replacement baskets from Amazon.
Question:	Hello. is there sunsun hw-304b 220v
Answer:	No
Question:	Does anyone have a problem getting this to work in a tank that isn't full? I filled the tank to prime then removed water & it stopped working
Answer:	You definitely want to pre fill the filter before starting it up (if you cant prime it hoses might be mixed up-suction return lines) I would also make sure the return tube is fully submerged at the top of the water. I personally have three 304b filters, one of them gives me issues like yours if the outlet tube isn't covered with water.
Question:	How do i know if my uv light is working? i put the filter together recently but i don't know if the light is turning on
Answer:	There's a little round button nest to the on off switch. It is actually not a bitton so dont press down on it. It is a window that will show when the light inside the filter is on.

User questions & answers

Question:	yesterday i cleaned out my filter and i put it back on but it wont suck in water from the pipe there is no pressure even after i pump it. why
Answer:	I came home and my filter was not running. I have had this for a month and it was running great. I cleaned out the filter, etc. and cannot get it to prime. I feel like I have tried everything! I filled the canister with water and it will not prime. When using the prime button, the water goes up to a certain point but does not prime.. Help!
Question:	What is the difference between the 1000, 1200, and
Answer:	What the others said. Personally I would get the largest you can afford. More filtration is never a bad thing. The 1200 and 1500 use the same filter pads.
Question:	Will filter work for a 100 gallon tank for my red ear slider turtle
Answer:	Yes. I use this for my CST in a 55 gallon tank. This is a great filter. Remember, it is more about the media you use than the filter alone. Experiment with media to see what works best for you. For my turtle, I have found that layering sponges in the bottom tray from coarse, medium to fine and then using Matrix bio media in the next 2 trays and then using carbon and an ammonia neutralizing carbon in the last two trays works wonders. It really keeps my turtle tank clean. This filter is easy to use, prime and clean. Plus it is very affordable. All canister filters are basically equal, the media is what really matters.
Question:	Will this include an installation manual and all the tubings? I am new to canister filters and I want to know as much as possible before purchasing
Answer:	Yes, though you would do well to check out some YouTube videos demonstrating the setup, as well as the steps to take to disconnect the unit from the tubes for cleaning. The manual that comes with the filter is a great start, but a little unclear at times.

User questions & answers

Question:	Is this filter effective for turtles
Answer:	In order to use this filter for a turtle aquarium, your water level must stay ABOVE the minimum water level line at all times, which means it needs to be within 3-4 inches of the top of the tank. This is a problem with most turtle tanks unless you have a Turtle Topper. Otherwise, it will work well for a turtle tank.
Question:	Could you add a sponge filter to the intake so it becomes Fry friendly
Answer:	Yes, you sure could! You could use sponge media or filter floss. Just be sure to clean or replace it whenever it becomes clogged.
Question:	Does it have a warranty
Answer:	Yes, it comes with a 3 year warranty on all manufacturer's defects. This does not include normal wear and tear or abuse, of course, but Tetra has a very liberal warranty policy. If you need warranty help, call 1-800-526-0650.
Question:	does this come with biobag and carbon filters or do u have to buy some
Answer:	Your initial purchase of the filter includes the Whisper Bio Bags ( 1 of them for the models 20, 30 and 45, 2 for the 70) and the Bio Scrubbers (again, 1 for the 20, 30, 45 models and 2 for the 70). You should replace your cartridges on a monthly basis, but can rinse them in between changes. The Bio Scrubbers should literally last forever, unless you lose them or damage them somehow. Wash these off in a bucket of tank water with a toothbrush.

User questions & answers

Question:	Is it really loud? I already had to get rid of one filter brand because it was so noisy
Answer:	As long as you maintain your filter properly, the filter remains reasonably quiet. You do not need to change the impeller as often as one person commented. I have multiple AC 110’s for years and never had to replace the impeller at all. I have been using AquaClear filters for many years. When you maintain your filter, rinse the impeller off. Do not use anything abrasive or it will compromise its proper function by throwing it off balance as it spins during operation.
Question:	Will the 110 fit on over the 1-1/4" tank edge of my 70 gal tank
Answer:	13 1/2"L X 6 3/4"W X 9"H with 4" of its width behind the tank.
Question:	do you need to replace the filter media in time, and if so, how expensive is the whole kit
Answer:	Doesn't anybody read instructions? Change carbon filter after 1 month, change sponge after 2 months, change biofilter (little ceramic donuts) after 3 months. Never change more than one filter at a time which is impossible if you read their system - so at least 2 out of 3 times a month you'd be changing 2 filters. Charcoal filters should be changed monthly - they should also be removed if you are adding medication to the tank or it will soak up/deactivate medications. Personally I think you clean the sponge very well as needed - NO soap- just clean water, same with the donuts. Perhaps having you change so many filters so often is quite the moneymaking deal but not good for fish.
Question:	Would the 110 be overkill for a 36 gal goldfish tank? Would the 100 work just as well
Answer:	I run (2) 110's on a 90 gallon tank of exotic goldfish. That means I'm running 1000 gallons an hour through the filters on high. I've raised exotic goldfish for 50 years - goldfish are the DIRTIEST fish there are. They produce more ammonia than any other fish. These filters work great. I have some mini's - now called the 20's - which I have had for 35 + years, and they still run as well as the day I bought them. I ONLY USE AquaClear. Best filter out there! They last forever because there are no moving parts to break. There is only a magnetic impeller. In 50 years, I've only had to replace one intake tube that broke, and it was my fault! I tried a canister filter once, and quickly went back to my Hagen AquaClears. Easier to use, and as big as they are, you can use any kind of media in them that you want to use. You cannot go overkill on filtration for goldfish.

Question:	on average how often should they be changed on a 3 gallon tank
Answer:	Hi Francis,The ReptoFilter is ideal for shallow water terrariums with as little as 2-3 inches of water. I hope this helps!
Question:	what are the dimensions of the bags
Answer:	You can fill the tank up to within a couple of inches of the top. The filter is adjustable as it comes with a hanger that is adjustable and two suction cups.
Question:	Is this the same as a Top Fin "Element" filter cartridge
Answer:	Hi denita clark, yes, but depending on the species you are keeping, and amount of water, we would recommend one for each end of the tank, most likely.
Question:	What direction should the "cloth" side of the filter face? (Outside or Inside
Answer:	I have bare bottom tank but u suppose it would if your sand was settled and your raise the filter so it's not sitting I'm the sand. I have read over the forums that sand can clog just depends on your set up.

Fluval FX4 is a high performance canister filter with many outstanding features designed to make aquarium fish keeping easier and more convenient than ever. This super capacity yet compact canister filter has a pump output of 700 gallons of water and has a filter circulation of 450 GPH, which both work to produce cleaner and healthier results. Filtering material can easily be placed in a removable stack of media baskets, which is at the heart of Fluval's multistage filtration. The baskets are precision-engineered to eliminate water by-pass, making filtration more efficient. The baskets can hold a total of 1 gallon of media and can be stacked in the precise combination of layers that will work best for your aquarium. Each one is lined with a foam insert for effective mechanical pre-filtering. Instant-release T-handles let you lift and separate the baskets quickly and easily, making routine maintenance simpler.

User questions & answers

Question:	is it quite
Answer:	Quite? don't even think about it. it gets louder and noisier at night times. normally, an under 30 [db(A)] sound lever is a safe and acceptable lever, but this one will make about 36-38 [db(A)] sound lever in the night. especially in the bedroom (away about 18 feet from the bed), you will need a sleeping pill to put you to sleep. I had one, but after 2weeks, I can't bear with it anymore longer, had to return it.
Question:	I have a 40 gallon tank for two read eared sliders. Would this filter be too strong or just right for my tank? Also, does it come with the hosing
Answer:	I've got it on a 55 gallon and it works fine! With turtles you want at least 3 times the filtration so 40 gallons of water needs a 160 gallon rated filter or stronger. Also it is recommended that you house your turtles separately as they are going to grow to be 8-12 inches long and are solitary in the wild! I recommend you join red ear slider turtle owners resto group on Facebook and they will have all the information on best diet best filters and best tanks for your turtles!
Question:	What do you have to replace for the filter media? And how often I don't believe what the company says about every month
Answer:	This is a very good filter, with "5" stages. The main foam padding, stage 1 and 2, can be rinsed out and reused about 3 times before it starts to get too worn. I rinse it in the water just pulled out of the tank to keep from killing the beneficial bacteria with tap water which contains chlorine. The soft portion of this foam pad does not hold up to even gentle squeezing out. I just rinse out the tiny filter pad, stage 3, at the top of the unit and have not replaced it yet. This thing is pretty durable and surprisingly expensive for what it is. Stage 4, the bio-media should not be replace unless they get damaged. Replacing the carbon media, stage 5, is a matter of choice. Many do not believe in it. I do. If you do use carbon media, remember it gets "full" rather quickly and should be replaced regularly, depending on the kind and amount of fish in your tank, it could last up to a month. Just think of the Brita filters. They are mainly carbon filters, and they make water taste yummy and free of junk. If you are really trying to save, you can buy loose activated carbon and make your own sachets with cheese cloth or those fill-your-own teabags. I've thought about doing that but have not tried it. I've been too lazy, and just purchased the carbon media bags, I believe they are about 8 bucks for 3. Hope that helps.
Question:	The Amazon description mentions "Ceramic heater core for even and efficient heat distribution". Does this have a built in heater
Answer:	The Fluval c2 power filter advertises that it has a ceramic heater core... unless its built in somewhere inside, its not visable period. so with that said, i still had my glass tube style heater and continue to use it with the power filter as i doubt that something i can not even see will heat the 20 gallon long tank enough for that fish i have.

Product description

The new 2016 SUN HW-704B external aquarium Filter system utilizes a multi-stage approach to filtration. Filtering aquarium tank water through four internal layered baskets filled with assorted filter media material provides extremely thorough biological, mechanical and chemical filtration. This canister draws water into the filter through an inlet tube and returns crystal clear water via an outlet tube (both supplied). the outlet tube is fitted with a spray-bar to help increase oxygen aeration levels within your tank. These filters are absolutely ideal for freeing-up space within your tank and provide a huge internal capacity for filter media, making them suitable for larger volume tanks. The four flexible media trays allow you to add other filtration media such as SUN activated carbons, ceramic rings or bio-balls (sold separately). by filtering your tank using the filter media, you will observe a vastly improved level of waste-free water through extremely strong biological purification. The filter's easy-access layered filter media basket's make it simple to customize your media choices to suit your aquarium and fish livestock needs. The built in UV sterilizer exposes passing water to lethal doses of Ultraviolet light, killing, sterilizing or otherwise irreparably damaging many micro-organisms. Your fish tank water is pumped past the UV light which is sealed inside a quartz glass sleeve which is designed to allow the maximum amount of UV to pass through the water. Maintaining the filter is very simple. The drip-free shut-off tap allows you to remove the filter and transport It away from your aquarium fish tank to an area more suitable for cleaning. Each filter media basket lifts smoothly out of the unit and can be easily rinsed through and returned to continue its operation.

User questions & answers

Question:	what is the tube ID dimension
Answer:	With hoses attached it would be very, very tight if it was me I would not use this cabinet. You need no less than 22 to 23 inches in height.
Question:	I live on the 2nd floor in an apartment building. We have frequent power outages that last from 2 seconds to .5 hour. Will this leak all over
Answer:	Yes it does but you must use the internal pump for the sterilizer to come on .
Question:	Why can't I find sunsun 704b replacement parts
Answer:	I put the bio balls in first. then the ceramic. finally the filter pads in the same layer. i only use 3 stages leaving room for something else like carbon bags. i love mine it works great.. very quiet so when you start to hear a very minimal hum coming from your tank it is time to clean it. and finally make sure you have a towel with you when cleaning it you will lose a very small (2-4 ounces) amount of water when you disconnect it.
Question:	What is different from the sunsun hw304B? Other than the shape of course
Answer:	No, the flow can't be adjusted. Actually it doesn't even have a power switch but turns on by unit being plugged into electrical outlet

Product description

The fully adjustable flow regulation feature on the Tidal Power Filter adjusts performance to a specific aquarium volume, type, or provide an environment for fish that prefer more or less water movement or oxygenation. Adjust the dial from anywhere between 450 gallons per hour down to a gentle 90 gallons per hour.



For over three decades, Seachem has been a company rooted in sound science. Our experience in the hobby and educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of our employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such passionate hobbyist - Dr. Leo G. Morin (Founder) - recognized the lack of available solutions to aquarists'.. This resulted in Seachem’s very first product: Cupraplex (today known as Cupramine). Over thirty years later Seachem is still approaching old problems in a new way.



Seachem’s philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.

• FLOW REGULATION: The fully adjustable flow regulation feature on the Tidal Power Filter adjusts performance to a specific aquarium volume, type, or provide an environment for fish that prefer more or less water movement or oxygenation. Adjust the dial from anywhere between 450 gallons per hour down to a gentle 90 gallons per hour.
• SURFACE SKIMMER: The surface skimmer on the Tidal Power Filter will capture the water from just below the surface, where excreted fish oils accumulate, as well as deeper in the tank to remove floating debris.
• ADJUSTABLE INTAKE FLOW: With Tidal’s dual intake, it pulls water in through the telescoping pipe below the surface and at the surface through the surface skimmer. Easily adjust how much flow comes from the underwater intake pipe versus the surface skimmer with the intake flow dial.
• HEATER HOLDER: A heater can be attached to the side of the Tidal Power Filter with an optional heater clip, allowing for better dispersal of heated water throughout your tank or aquarium.
• MAINTENANCE ALERT: When filtration media becomes clogged with detritus and affects the flow of water, the Tidal Power Filter redirects water around the filter and back into the aquarium through an outlet on the side. The redirected water then pushed up the blue maintenance alert on the top of the filter, signaling that the filter needs to be cleaned.

Seachem Tidal Power Aquarium Filter - 35 Gallon Large Fish Tank Filter

• Ventilation slots in the lid of the filter and aeration grooves in the outflow ensure that water returned to the tank is fully oxygenated and maximize gas exchange during filtration.
• The pump pushes water up into the basket of the filter, entering through the bottom of the basket and being pushed out the top. A bottom-to-top flow ensures that water comes into contact will all filter media, and cannot go around or over filter media as with hang on back filters with a back-to-front flow.
• Over time, filtration media can become clogged with detritus reducing or obstructing the flow of water through it. When this happens in Tidal filters, water is redirected around the filter and back into the aquarium through an outlet on the side. The redirected water pushes up the blue maintenance alert on the top of the filter, signaling that the filter needs to be cleaned.
• The surface skimmer will capture the water from just below the surface, where excreted fish oils accumulate, as well as deeper in the tank removing floating debris.

Features:

• The filter basket has a huge capacity to hold filtration media of your choice in the configuration of your choice. All Tidal Filters come with Seachem's Matrix bio-media to get you started.
• The basket is fully removable and snaps into the lid of the filter for easy and drip-free transit to a sink or hose for cleaning.
• Self-priming pump means there is no need to fill the filter basket with water, start a siphon, monitor the filter, or any of the other headaches of starting a new filter.
• The self-cleaning, corrosion-resistant impeller is suited for both saltwater and freshwater environments. This cuts down on maintenance and makes the filter suitable for a wide range of environments.
• A leveler on the base of the filter lets the filter adjust to a variety of aquarium styles.
