User questions & answers

Question:	I have the fluval flex 32.5 gallon tank. which heater should i get? thank you
Answer:	Where do you live? I live in FL where the average temp of my fish room is 75. I have M200 (200W rated for a 65 gallon tank) on my 75 gallon tanks. If you live in Maine, the average temp is probably 60-65 of your fish room. you will need the M300 ( 300W rated for 80 gallons) or maybe 2 of them to heat the same 75 gallon tank. with that said, I think you will be find with the M100 or M50 will be fine for your 32 gallon tank. just make sure they will fit. when you set it up, put the heater in the tank, let it sit for a day or at least a few hours before you turn it on.. see what temp the tank is, turn the heater on the lowest setting and slowly turn it up to the match the tank temp. let it sit there for a hour or so, then set it to what ever temp you want. Don't trust the dial that states what the temp is, it may be off by 1 or 2 degrees. Be sure to monitor the temp for a few days to make any adjustments. Heaters will not change the temp of the tank instantly, it may take a few hours.
Question:	How long does it take to heat a 15 gallon tank
Answer:	The instructions say: "Wait 30 minutes before connecting to the electrical outlet. This allows the heater to adjust to the aquarium water temperature. Note that it may take up to 12 hours for the eater to attain the water temperature you have selected." That being said, my experience is that it is quite a bit faster than that. Of course, that depends on what temperature the water started at! (i.e., how cold is your room). Please note that thre 50 watt model is rated for 15 gallon MAX. That means if you want wiggle room, you might consider the 100 watt version. Again, however, my experience is that the 50 watt was adequate for my 15gallon. But my house is not cold.
Question:	Can it go compleatly under water
Answer:	Yes it can, "Cord and all" (but not the plug) according to the Fluval representitive I spoke to at Fluval customer service. I've had mine completely submerged ever since and havnt had any problems. Just remember not to keep it on if you have to empty tank water behond the bottom line.
Question:	Can you adjust the heat with this heater? Does it have a dial
Answer:	Yes, it's easy to adjust, and keeps the tank a constant temp.

User questions & answers

Question:	Would the 500w be ok in a 65 gallon tank that will be eventually used in a 125 gallon
Answer:	It took mine under 15 minutes to heat my 2.6 gallon tank from 74 to 78 degrees. If I may, I would suggest that you check out a 50 watt heater, the 25 w is meant for 2 to 4 gallon tanks.
Question:	How big is this controller
Answer:	Great Question.I have mine set at the default of 78 degrees, and if I unplug it and plug it back in it goes to the default setting of 78 degrees. I have not tried it at other temps to see how it responds. Worse comes to worse, 78 degrees is a pretty optimal temp for just about all normal tropical and marine fish.
Question:	Where is this heater made
Answer:	It works really good on our 50 gallon tank, room temperature range from 60 to 75 degree.
Question:	Can the 100 watt be used in a 20 gallon tank
Answer:	I'm using it in a 3 gallon Tetra Cube. As long as it's submerged horizontal or vertically, and not touching substrate, it'll work. The heater is 6.5" tall x 2" wide. I like it because, it heats to a set temperature; if the tank is too warm, it shuts off. I've been using it for a month, checking with a thermometer, and it's been spot on 80, as set for my Betta.

User questions & answers

Question:	The hearter reading seems to be different than my aquarium thermostat. Anyone else got same problem
Answer:	Yes! It’s always different. It’s always warmer than the thermometer. But my fig and plants are doing great so I guess it’s okay.
Question:	Can this be kept on
Answer:	ABSOLUTELY! It is designed to be plugged in, and it monitors the temperature 24/7.
Question:	Anyone try a protective guard/cover on this? Concerned re fish safety/scalding; thnx
Answer:	I don't believe the heater gets hot enough to scald the fish. The heater only lets the water get 2-3 degrees cooler than the setpoint (if I set the temperature to 75 F, the heater will turn on at 72 or 73 F), so it doesn't need to work hard to get the water up to temperature. Also, water is an excellent conductor of heat, so if the outside temperature of the heater is hot enough to scald the fish, then all the water is probably hot enough to scald the fish.
Question:	Why is the heater blinking ll? i just plugged it in this morning and it is warming but blinking red ll. is it defective? please let me know. thank
Answer:	If you click though all the temperature options, and go back to desired temperature, it should stop flashing LL and show you the temperate it is at instead

Perfect for freshwater and saltwater aquariums and terrariums

• Super-flat design. Fully submersible, modern design for energy efficient Aquarium and terrarium heating. Includes reversible holster/bracket, which allows heater to face inward or outward. See the product images to determine the best neo-therm size for your tank.
• Accurate, one-touch system. Simply set temperature between 66-96°f with one touch and the neo-therm electronic thermostat will maintain Tank temperature within +0.5°F. Led displays both set temp and actual temp, simultaneously.
• Ultimate safety and reliability. Integrated thermal protection circuitry prevents heater from overheating. If you forget to turn it off, the neo-therm will automatically shut it down.
• Virtually indestructible. Unlike cheap, glass heaters, the neo-therm is a resin/thermoplastic heater with a shatterproof outer-casing. Made in Poland and includes a 3-year warranty.
• Manufacturer You can trust. Most manufacturers rate their heaters on the ability to raise an aquarium 2-3°f above ambient temperatures. This is unreliable and misleading, as the average home fluctuates 2-3°f or more throughout the day. Cobalt rates The neo-therm on the ability to raise a tank 11°f above ambient temperatures, so you will never have to worry about overworking the neo-therm or it keeping up!

User questions & answers

Question:	About how long should it take to heat a 70 degree 5 gallon tank to 78 degrees
Answer:	No , just buy a heater made for reptiles.
Question:	Does it retain setting if there is a power failure
Answer:	Thanks for asking! You typically want around 3-5 watts per gallon of water, depending on your room temperature. The heaters are calibrated to the average room temperature of 72 degrees. So a 200 watt heater can handle up to a 75 gallon tank, or pretty close, if you have a warmer house and go by 3 watts. In a colder home, say, one heated around 65 degrees, it is capable of up to a 40 gallon tank. Let me know if you have any other questions.
Question:	How many gallons will this heat
Answer:	Theres a red led that's turns on when its heating. It's only on when the heater is heating, if the water temp is at the heater set point then it turns off
Question:	Would this work for a four gallon or is it to big
Answer:	It should be fully submerged at all times, and can be anywhere in the tank. You can place it vertically or horizontally, but do not bury it or allow anything to press up against it.

User questions & answers

Question:	Would this heater be ok for a 10 gallon tank
Answer:	The part that reads temperature is pressed up against the tank glass. Which means in actuality it is reading the tank temperature. It’s not unusual to have different thermometers be a degree or two off. I am not an expert but I would rate this thermometer is the most accurate that I’ve ever owned
Question:	whats the lowest temp it can go
Answer:	Flashing is warning you that the current temperature is higher than the highest temp you set or lower than the lowest te, you set. if you want it to stop flashing, just set the left small number greater than the current temp and the right small number less than the current temp. Here is the step: first short press the "fish" the left small number will flash, then press "up" to make it greater than the current temp, then short press "fish", the right small number will flash, then press "down" to make it less than the current temp. Done.

How to choose right size heater?

• Rule of thumb is between 2.5 and 5 watts per gallon of water volume. This can obviously vary depending on how cold the room is that your aquarium is in, and how large the tank is.
• For example, if you have a 5 gallon tank, you need to heat the water up to 10 degrees above room temperature. The suggested heater size is 50 watts. However, if your home is on the colder side at 65°F and you need to raise the water temperature by 15 degrees, then consider upsizing to the next available heater at 75 watts.
• 500 Watt, for 60-120 gallon tank
• 800 Watt, for 120-180 gallon tank
