Help keep your pond ice-free with the Tetra Pond De-Icer. Designed as the perfect winter survival solution for fish, it heats up to melt ice around it wherever you place it in your pond. A layer of ice on your pond traps wastes and gases that are toxic to your fish. By melting some of the ice, it allows the trapped gases and toxins to escape and keep your fish healthy through the winter. Thanks to its natural stone finish, it looks great in any outdoor naturalistic pond environment. It works with temperatures as low as - 20°F, and has an energy efficient thermostat that automatically shuts off after melting the ice. Plus, it includes a 15 foot cord, works with 300 watts of power, and is UL listed for safety.

For most of the winter we used a high output pump to keep our water from freezing, but we got a forecast for below 0 and didn't want to risk it. We ordered this, got it in before the big freeze came that was predicted. Works as it says!

These work great have been using them for years in several of my ponds plus they have a 3 year warranty.
Dead in the water
on Oct 15, 2020
The deicer from Terrapins did well for two winters but did not make to its third year warranty. My electrician installed 2 twenty amp circuits for the pond and he said the heater was tripping the circuit. He demonstrated by plugging the deicer into the new outlet and it tripped. Then he plugged in his corded electric drill and it did not trip. He said the heater or its cord had a short. When I pulled it out of the pond I shook the head and it had water inside. How do I collect on the warranty?

So I put this in my small pond about 24 hours ago. The temperature outside is still in the mid 30s at night... And mid-40s and 50s during the day..so obviously, I put it in the pond a little prematurely, it however, raised the temperature of my 60 gallon water garden upwards of 85° F in 24 hours or less. Did not realize this until after dark tonight.
I'm hoping that my fish are still alive after being exposed to such a huge temperature increase in such a short amount of time. I unplugged it and ran cold water from my hose to decrease the temperature down to about 70°. I will check on my fish in the morning during the daylight. I really hope they are alive.

I unplugged it and ran cold water from my hose to decrease the temperature down to about 70°. I will check on my fish in the morning during the daylight. I really hope they are alive. Given the reviews I keep reading tonight about this contraption, I'm wondering if it has a bad or highly inaccurate thermostat. Even the people that are ranting and raving about it for being a great product are uploading pictures of their ponds with 4ft or 5ft diameter holes of unfrozen water.... Product is only supposed to create 2-in diameter hole around itself... Meaning given the fact that this product is only about 6 in long and 4 or 5 in wide, people should not have anything bigger than a 10 inch diameter hole where ice does not form. I'm glad that chewy.com is sending me a new one without actually making me send back this one as I'm still probably going to use it in the same 60 gallon pond (that is only 2.5ft deep deep) and put it on a timer on the nights that it gets really cold and have it only turn on every 3 hours... for durations of 30 minutes to 1 hour along with the new one that hopefully works as it is supposed to.... As I was worried that I would need a submersible heater along with the replacement floating heater to keep the pond from freezing at the bottom. Just like I prematurely put this de-icer into the pond I prematurely gave this product three stars not knowing if the new one is going to have problems too. If I can change my review after the new product comes I will… more

My fish are so happy to not be frozen in. It is a very nice compact heater that does an amazing job.
Worked great for me
on Mar 23, 2020
I waited until spring to write a review. I bought in the fall & had running all winter long. This worked great for me. Live in zone 6, and never had a spec of ice form across the entire 5 foot pond. On warmer days I unplugged otherwise the temp would climb above 50F. My pond is 5Lx5Wx3D (feet). My goldfish and myself pleased with the purchase.
Not worth the price
on Jan 17, 2020
Here is a pic of my tiny water feature with this de-icer in it. Today it is +11 & this is barely fit to de-ice for my stray & feral felines to drink from. Pond is only 18" deep & approx. 5'x3'. I would not recommend. Expensive to run for what you get.
Small De-icer Lasts Only One Year
on Jan 22, 2020
Have used a number of these over the years, to help "de-gas" the pond for the goldfish and mostly to keep at least a small area for my feral felines to drink from. However, they only last one year... no matter what brand you get.
2 out of 3 IS bad
on Nov 12, 2019
Ordered two last November, one arrived DOA and was replaced by the wonderful people at Chewy.
After using the two de-icers for one season, another one of them no longer works.
When it works, the product does keep a hole in the ice open. (even in negative temperatures with a foot of snow on the pond) However, this product is not reliable and I wouldn't feel comfortable going on vacation and depending on this to keep the pond from icing over.
Deiced my koi pond overnight

Worked fast my fish love it they constantly swim underneath it. Only 300watts so it doesn't use much energy like the other ones I found in store that use 1500watts. All the fish need!!
