User questions & answers

Question:	I have a small pumphouse...pump not below frostline...is set in the hole will it keep area from freezing
Answer:	The Farm Innovators Floating Pond De Icer is designed to keep your decorative water garden free of potentially harmful surface forming ice in cold climates. A virtually indestructible cast aluminum body houses the powerful 1,250 watt heating element which quickly opens a hole in the surface of your pond allowing harmful gases to escape. The Farm Innovators Floating Pond Deicer is thermostatically controlled and turns on only when temperatures drop below 35°F. The Farm Innovators Floating Pond De-Icer comes with a 10' power cord and is safe for rubber and plastic liners.
Question:	does it float
Answer:	The bottom of the heater gets hot however it does not sit fully flat due to the power cable entering thru the bottom.If your crock does not have water in it and the temp goes below 35 degress it will remain on so keep that in consideration.It gets hot enough that it does melt ice. However depending on the width and depth of your crock it may not unfreeze it now or keep it totally unfrozen. I have it at the edge of my pond which is about 6 inches deep and right now with the below zero weather we have been having it is keeping a hole about 1 foot in diameter. Warmer temps in the 20's or so it keeps a larger area unfrozen.
Question:	The ice has already frozen. Can I put the rock on the ice while plugged in and wait for it to melt though
Answer:	No
Question:	I have a fish pond, some 500 gal, with mollies, goldfish and pictus catfish. Can the thermostat setting be chg'd to come on, at say 40 deg
Answer:	Yes.

User questions & answers

Question:	I live in zone 5. I have a 100 gallon pond which is 18" at it's deepest point. Will this product keep it from freezing solid
Answer:	Yes, both the inner and outer sections are on swivels.
Question:	What wattage should i buy for a old corner bath tub im using as a duck pond? It's 19in deep. I don't know how many gallons. I live in a zone
Answer:	Each of the fins attaches to the pole with a set-screw and then when all the fins are attached it sits on the sealed bearing, which makes all the fins spin together, it is very well made and moves easily in the wind, but needs to be in a slightly windy area. Hope this helps.
Question:	Can i use this in zone seven with a 50 gallon outdoor plasic gold fish pond? Should i keep my pump working to for circulation? Thanks
Answer:	Make sure the spinner is level. If you have used a lubricant in the past, dirt and grime may have built up. I suggest to take the spinner apart and clean out the ball bearings with something like WD-40 and leave it at that.
Question:	I have a very small outdoor goldfish pond/small fountain. Only about 15 gallons and only about 13" deep. Will this work and be safe for the fish
Answer:	It is top heavy for stand wobbles in high wind. The copper is terrible it spots in rain and has to be cleaned if you want the shine. I am very disappointed for the price. I should not have any worries at this price.

User questions & answers

Question:	What is the average monthly cost to run this heater? I have heard that 1,500 watt heaters can cost up to 75$ a month to run
Answer:	How much of an area it will keep open depends on the size of the pond and the outside temperature. It's purpose is to keep a hole in the surface, for gas exchange. I've used it in a very large pond and found it kept a sizable area open though, unless extremely cold temps last for days.
Question:	Our pond is only 55 gal. Is this heater ok to use? Or do you know a model that would work
Answer:	Thanks for asking! Yes, this product floats. For more help contact TetraPond at [email protected]. We are happy to help!
Question:	How long is the power cord
Answer:	No. I have had customers try this. It does not work. Boil some water on the stove and pour onto the ice until you melt a hole to float the heater in.
Question:	I just bought this and had it in my pond for a day & noticed no change. How do I know if its working? It makes no noise & doesn't seem to get warm
Answer:	As the customers stated, no, you cannot set this like a heater. Your mollies and pictus cannot be housed outdoors over winter, although the goldfish can be.

User questions & answers

Question:	Does this cord have a two- or three-prong plug
Answer:	This item is only 100 watts and only 'turns on' when temperatures are around 32 degrees. Its operating cost would be minimal.
Question:	Can you us an extension cord with this? My pond is not that close to the house
Answer:	We have a pond that is around 800 gallon. It works in ours. This heater is only made to keep a hole in the ice so all the gasses from decaying stuff under the ice don't kill the fish. Hope this helps. Richard
Question:	How do you turn it on
Answer:	Although I have not measured it, I'd guess it is at least 10 feet. Very long, but it tends to "remember" the coil shape. I put rocks on the cord to keep it from pulling the unit towards shore. I would highly recommend this product for keeping a hole in the ice over the winter. I've bought 2 in the last 7 years and the only reason for the second one was that I dropped the first one and cracked it, rendering it useless. I've also discovered that when the temps get close to or fall below zero, placing a black plastic tarp over the unit will help keep it from freezing up. I have seen it melt and maintain a hole through 6-9 inches of ice. Another thing to remember that once the ice forms and you place it, future snow falls will encase the cord in ice and you will not be able to move it. Allow additional cord so it cal maintain contact with the water.
Question:	Is it 120 watts or 12 watts? what does "12 watts of heating power" mean
Answer:	The unit is a de-icer. Is your pond cover with ice? This is my second unit, the first one lasted 10 years with no problems. I have a Koi pond that is 3,000 gallons and 4 foot deep in the center and the pond with this cold weather is covered with ice 12 inches thick. If your pond is ice covered they suggest you drill a hole thru the ice and place the unit over the hole, it will eventually melt the ice surrounding it, just as mine did. My unit keeps a hole in the 12 inch ice as big as the entire unit. Again this is not a pond heater, it is used to keep an open hole in the ice so the gases that are harmful to the fish can escape. The unit doesn't make any noise and it only gets warm on the bottom when the thermostat calls for heat.

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

Question:	Having trouble keeping the lines between check valve and stones from freezing... Help
Answer:	Yes. I think it would work great. The airflow is adjustable and can be set to the amount of air you want.
Question:	How many gallon of water can this pump serve
Answer:	It doesn't sound like a air stone issue, make sure that the airline filters are going in the right direction and blow on the tube to see if the stones work , also put pump setting on high and feel if the air is coming out of the pump if not it’s a faulty pump.
Question:	How can I protect the pump when exposed to the elements
Answer:	You can purchase just a diaphragm kit, PondAir 2 retails for $7.99, while the PondAir 4 retails for $14.99. You can contact the manufacturer for purchase or a dealer near you at 1-866-424-7629.
Question:	How much air line comes with the pump? How large are the air stones
Answer:	I live in Georgia but I leave mine out all year long. I have a large clay pot that we layed down that we placed the motor inside to keep it from the elements. The outside seems to be waterproof but we didn't want to take any chances. I purchased it in June 2016.

User questions & answers

Question:	will this heat the water
Answer:	10 to 12 ft I'm guessing but it's pretty long.
Question:	how long is the power coed
Answer:	I think would work fine. It does not get too hot. Basically just keeps ice from forming right at the de icer. But I'd seal the cord going into unit better.. As mine seeped water into it.
Question:	will this work in 3,500 gallon pond with bubbler
Answer:	Mine does the same thing. It took me a while to figure out what was making the noise. I guess it's just expanding and contracting from heat/cold.
Question:	My experience with pond heaters is that they seem to die quickly. How can you tell if this heater is working if there is no light indicator
Answer:	actually any pond size because it heats up just around the de icer. to keep a hole open in the pond. does not heat the pond itself. I use a bubbler that bubbles up around the de icer. works great to keep a open hole in pond. my pond is about 3500 gallons.

User questions & answers

Question:	Will this work for a 5, 000 gallon Koi pond? Getting ready to set a pond up and want to make sure i have the right things for a under ground pond
Answer:	I purchased this for my chicken waterer that I made from a 35 gallon square trash can with horizontal nipples on three sides. It works awesomely! I was worried the 250w heater was not going to be warm enough, so I went with this 500w heater. I have it floating. My nipples are less than twelve inches from the ground. When the garbage can was full of water a few days ago and temperatures dropped to -3 F degrees, the water was nice and warm compared to the outside temps. This heater exceeded my expectations!! Based on my experience, I would purchase only one 750w for your 55 gallon drum. I know you were asking in July, but my experience is based on this winter. Perhaps this will help others. I hope you made the right decision.
Question:	What is the warranty on the pond deicer Aquascape
Answer:	Solar power doesn’t have a steady current (it fluctuates) and therefore it will not work properly.
Question:	Does it help to keep water in the pond between 60 to 68 degree F
Answer:	Adding one comment to the earlier answer. If your water level gets low (this is a fairly tall heater so you should never go below about 6" of water) and the outside temp is low, there is no safety turnoff. So if it's 30 out and the livestock drink the tank down to a couple inches of water, the heater will glow red until you add water. Not a problem with the product since it can't tell if it is surrounded by cold water or air, just a tip to keep the water at a minimum depth so you don't waste power.
Question:	Hi. Does this heater ad a lot to your electric bill?? Thanks
Answer:	I don't know what kind of breaker you're on. If you're on a 10 or 20 amp breaker, it all depends on what else you've got on that circuit. If you're on 120 volt AC current and you add two 750 watt tank heaters, you've added a 25 amp load to your breaker, and it kicked off. I'd advise putting each heater on separate breakers. They may be simply overloading it. Despite my glowing review, which was based on last year's mild winter, this year we have more sub-zero weather. The 750 watt heater in a 75 gallon tank crapped out on me at -10F and so did a separate 40 gallon tank with the 500 watt heater. I then used an old 1,000 watt floater I had around, and that died last night. I had to get two submersible 1500 watt heaters at the local feed & grain. As I type this, it's going down to -12F and I just blew the house breaker I have one of the tank heaters plugged into. It's a 1902 house that got electricity in 1931 and an oddly configured 1964 upgrade. The parlor lights, porch light, and outside outlet are all on one 20 amp circuit as well as pet heaters for two outside cats, and a heated water dish. I'm on my way out to unplug the cord, dig 50 feet of it out of the snow, and try plugging it into a 20 amp plug in my shop in the barn - have to make sure the other heater, which is plugged into a barn outlet, isn't on the same breaker. Trouble is, if it goes out in the night, I won't know it. Well, good luck to us all.

User questions & answers

Question:	How much does it rust
Answer:	It’ll rust a little but not enough to interfere with its function.
Question:	I have a 210-gallon hot tub; will it keep it from freezing in a power outage with temps close to zero
Answer:	No it will not keep the complete tub from freezing.
Question:	Using to keep ice bath from freezing outside, will it still work if its sitting sorta tilted & not flat
Answer:	I don’t know what an ice bth is.This heater drops to the bottom.. I don’t see any reason why it would matter if it isn’t a flat bottom or if the heater is at an angle as long as the water space is large enough for the heater to be submerged. But I don’t actually understand your situation. Sorry I can’t be any more helpful.
Question:	Can this be used in a pond that has turtles in it
Answer:	Yes. I have used them for years in a250 gallon plastic turtle pond over the water pump bottom filter. They only last about 1-2 years though. My turtles sometimes huddle around it. Chicken wire cage is probably a good idea though. But won't burn them under that much water. Don't heat it for very long out of water. Only use with a GFI outlet.

User questions & answers

Question:	Does this actually work and is it well on your electric bill
Answer:	No. You hook it into one you already have.
Question:	Have a 38" x 14" deep 35 gallon preformed plastic circular pond with frogs that showed up this summer still in it. Will this be too big/hot
Answer:	My pond is 1000 gallons in Wisconsin and it keeps it warm enough to keep the koi in all winter
Question:	Can I use this in a hot tub until the repair man can put in a new heater? Will it harm the fiberglass bottom
Answer:	Yes, too big. We bought this and used last winter in our 2000 gallon koi pond and it worked well, keeping one end of the pond from freezing and an opening about 3 foot in diameter around the heater. My guess is that your estimation of 50 gallons is low (even for a small pond) but even if 100 gallons, you will probably overheat and kill your fish. Reference: 50 gallons is only about 6.7 cubic feet (a large indoor aquarium).
Question:	How do I know if the unit is on? I have it in the pond and it doesn't even feel warm. Does it turn on at a certain temperature
Answer:	From the Lagunapond website: "The light is red when the unit is warming up. Once the de-icer reaches its pre-set temperature, the light will switch to green. If the unit needs to heat up again due to a change in water temperature, the red light will come back on."
