13 best pondmaster uvs

The Pondmaster UV Sterilizer (often referred to as Pondmaster UVs) is a product used in water treatment for ponds and water gardens.It falls under the category of outdoor decor and is typically found in the Patio Lawn Garden section of stores.

UV sterilizers are devices designed to kill or deactivate microorganisms in water by exposing them to ultraviolet light. In a pond or water garden context, these microorganisms can include algae, bacteria, viruses, and parasites that can affect the water quality and the health of aquatic life.

The Pondmaster UV Sterilizer works by passing water through a chamber where it is exposed to UV light. This light disrupts the DNA of the microorganisms, preventing them from reproducing and thus helping to control their population. This leads to clearer and cleaner water, which is essential for maintaining a healthy and aesthetically pleasing pond or water garden.

It's worth noting that while UV sterilizers can be effective tools in water treatment, they are not a standalone solution. Proper pond maintenance, including regular cleaning, appropriate filtration, and water testing, is crucial for maintaining a balanced and healthy aquatic environment.

When considering a Pondmaster UV Sterilizer, it's important to choose the right model based on the size of your pond and the specific needs of your water garden. Additionally, following the manufacturer's instructions for installation and maintenance is crucial to ensure the product's effectiveness.

Please feel free to ask if you have any specific questions about Pondmaster UV Sterilizers or related topics!

Pondmaster 02940 40-Watt Ultra Violet Light Pond Water Clarifier - DNR02940 - Black

PONDMASTER

Based on 259 reviews Check latest price

Product description

Submersible 40 watt Ultraviolet (UV) Light Pond Water Clarifier for use with pumps up to 3000 GPH, in ponds up to 6000 gallons. Kills suspended algae with UV light. Water can be pumped through the UV light and then into a biological filter (sold separately) where debris and dead algae can be trapped and decomposed. When installed correctly, UV lights are very effective at eliminating green water pond problems. This UV light has a 3/4 barbed intake and outlet for flexible tubing and is equipped with an 18 ft power cord. The soft blue halo light rings show that the unit is working. The vortex flow design increases the exposure time of the water with the ultraviolet light and the slim diameter brings more of the water closer to the intense UV rays making the process more efficient. These clarifiers can be installed submersed in the pond or outside the pond. UL listed."

User questions & answers

Question:	does this come with bulb or is that sold seperatly
Answer:	It comes with the bulb.
Question:	why dose the uv light stop working after a week
Answer:	I am not an electrical expert and I have never in the three years of operation of the Pondmaster 40 watt UV clarifier had multiple bulbs burn out. But, two possible answers occur: 1. You have been unfortunate enough to purchase defective replacement bulbs. 2. The other possibility is that the transformer is defective and is burning out the bulbs. My suggestion is that you contact Pondmaster and request a replacement transformer. It readily threads off the end of the unit. The manufacturer will undoubtedly request the return of the original. Depending when you purchased the unit, the transformer may be replaced free of charge. One thing to be alert to is the presence of water inside the glass tube that houses the UV bulb itself. That should have NO water inside. Water inside the tube would indicate the rubber seal at the end of the protective glass tube is either broken, damaged or was not properly/fully seated at the end of the transformer housing. Be certain that you have disconnected the electricity before you handle the unit. The bulb must NOT be illuminated when you disassemble the unit. UV light at that intensity will damage your eyes. Hope this helps.
Question:	How to install
Answer:	Thanks for your question. Basically you plumb the unit into the tubing that's being pumped water from your pump and then plug it in. Anything specific will depend on your application's needs. If you need more help you can call Pond & Garden Depot toll free at 1-866-305-5459Cody H.Customer Service
Question:	do the 4 - 90 degree bends, 2 in & 2 out, adversly affect (increase speed/restrict volume/force pump to work harder) the water flow to the waterfall
Answer:	Every 90 degree bend adds about a foot to the total dynamic head of your system. This means that flow is reduced the same as raising the water up 4 foot in height. The length of your tubing and its size also affect this number. However, the important thing to remember is that UV units work best when the water flows through them slowly and allows a longer contact time between the water and the UV. Many customers opt for a separate small pump to power their UV rather than try and run water through too fast with their existing pond circulation system. A general rule of thumb is that adding a filter or a UV will lose about 15% of your flow of water. hope this helps. John from Graystone

User questions & answers

Question:	Is the UV bulb included with the device or does that have to be purchased separately
Answer:	Hello. Our UV includes the bulb and quartz sleeve. Thank you, Marvin Gardens Store 888-758-6191
Question:	Would this be suitable for a 125 gallon outdoor pond
Answer:	Hi Yes it will be. This is rated for pond up to 1500 gallons. You may want to look into the Tetra 5 watt UVC Thank you.
Question:	I have a small pond (500 gallon) where the water has turned green. Will this be effective for clarifying my water? Safe for fish
Answer:	Yes this is safe for fish. Main thing if you have fish is to make sure the fish load is not more than the size of pond can handle. Also that they are not being fed too much. Having plants in water is also a help to quality.
Question:	How long is the warranty
Answer:	hello Walter, the unit is warranted for one year. I am not sure the bulb is covered for more than 3 months. I would have to check that.

User questions & answers

Question:	What model number is the replacement bulb
Answer:	upc#025033129725 model#12972 item: 20 watt replacement lamp koi smart pond supply 561-408-2739
Question:	Does this product come with any type of warrenty
Answer:	Not sure about a warranty, but it the only thing that can really go wrong is for the uv build to cease to be effective, and that would not be a warrantied part anyway. It will continue to shine, but will not continue to kill the algae. I run mine all summer and pick it up in the fall, and am on my second bulb in probably 5 years.
Question:	how long does it take to clear up your pond on average with the Pondmaster
Answer:	Thanks for your question. Most customer's report satisfactory results in approximately a week but we've heard of customer's saying they got over night results. Make sure you buy the right size unit for your pond and also have the proper waterflow from the pump. If you need more help you can call Pond & Garden Depot toll free at 1-866-305-5459Cody H.Customer Service
Question:	Can I use this for a jacuzzi
Answer:	The fittings could be adapted but the water would move through to fast to be effective. The manufacturer is very specific about the amount of water flow over the light as too great a flow does not allow enough light exposure to the water passing around and through it. GREAT sterilizer for a medium size pond with proper sized pump.

Question:	I'm seeking the replacement bulb for the pondmaster uv 20watt sterilizer however when i read the reviews it seems this bulb is a problem
Answer:	Sorry Amazon. We buy all of our bulbs for our pond sterilizer from 1000 bulbs.com. Good price and no problems with the bulb.
Question:	So to be clear, this is the actual Danner Pondmaster bulb correct? Not a knock off brand
Answer:	Yes, this is the actual bulb. I bought the UV Light unit from Amazon and I buy the replacement bulb from Amazon. No problems, I got it quick and it works great.
Question:	how long is the bulb
Answer:	I didn't measure it. It was an exact replacement for the UV bulb in my OASE filter. I don't believe there was any choice in size, it appears to be standardized. If you are thinking of replacing a bulb with higher wattage, it may not work properly, unless the manufacturer says it can be done without modification. You woudl also have to replace the transformer.
Question:	Is this rated at 900 hour ( as described on this listing) or 9000 hour
Answer:	We replace ours once a year in April and the pump runs 24 hours per day. The 9000 hours is more accurate

PONDMASTER

Based on 5 reviews Check latest price

Product description

The Pondmaster Supreme 02910 UV Clarifier is the only submersible unit on the market. It can also be used outside the pond when connected with tubing. The ultraviolet light helps to inhibit algae from reproducing by damaging its DNA. It also kills parasites in the water. The quartz sleeve and UV lamp are not installed and are located in separate boxes inside the main box. To install the sleeve insert the round end into the main body until the rubber ring is all the way down into the main body. A flange will prevent the ring from going any further. It will rest against the main body. To install the bulb, unscrew the transformer from the main body. Align the center slot and pins with the mating connector that is inside the transformer. Push the bulb down firmly. Slide the bulb and transformer into the quartz sleeve and screw the transformer onto the main body. Hand tighten until snug so as to not over tighten.

User questions & answers

Question:	Can i use this UV clarifier in different country that have 220V power
Answer:	I would doubt it. My clarifier is plugged into a 120. That question should be answered by the manufacturer.
Question:	What are the dimensions / size of this
Answer:	A little larger than a paper towel center tube.
Question:	How many gallons per hour can this handle
Answer:	This pump handles up to1500 gallon ponds at 700 gph. I have a 1000 gallon pond and this uv clarifier will clear up water within a day.
Question:	Can this just lay in the bottom of the pond
Answer:	It can lay on the bottom of the pond, but to have it do any good, you have to pump water through it. The UV light inside will kill the microbes that cloud the water, but if you don't move the water through the chamber and past the light source, it won't expose the UV to the water you're trying to clean.
