Rated 1 out of 5 by from Poor design Over the past 3 years I have used this De-Icer. The first one leaked at the seams and water got inside, after the first year. They replaced it under warranty and yet again the second year it leaks and filled with water, again. Now in need of another De-Icer. They will not warranty the second one and said I would have to purchase it. Not happening on a product I believe they know is faulty.

Rated 1 out of 5 by from don't get this I had bought this and ended up coming for a replacement as it quit during winter. This winter my replacement one died as well, the warrenty isn't good now. I'm told they're no good for Canadian winters, after the fact.

Rated 2 out of 5 by from Works but doesn't last Works for a season then fills with water just into next winter. After that it trips out the ground fault.

Rated 1 out of 5 by from Worked for less than one season We bought and used the deicer for half of last winter. After our first cold snap this year, we woke to find it frozen in the ice. After poring hot water on it to remove it, I touched the underside and it was not even warm. I know it was getting power as that same outlet is used for our aerator. Now I have to pay to send a faulty unit back but even that does me no good as we need a heater NOW to save our fish - not in weeks from now. As I read various reviews online, way too many people have had this same problem. It is clear this is a poorly made deicer and Tetra should stop selling it.

Rated 3 out of 5 by from Water leaks in rock I have owned 3 of these. I have had two get water in it. I was close to my 3 yr warranty and no receipt but had box and tetra pond replaced with no questioned asked. The one they warranties two years ago was a different problem but after two years I have water in this one now. Just called cust svc and they are sending a new one out but with no further warranty. The warranty is based on original purchase. But they did a one time courtesy so tetras cust svc is #1. I asked about water problem if anything being corrected to solve issue and she that would be an engineering concern. I am going to write the company regarding the issue. If the deicer fills with water I will probably try a different brand. For now I'll stand by tetrapond. Love the deicer.

Rated 3 out of 5 by from Has worked good for the past two years. Plug in and leave alone. Heater works good. I have water inside the rock now. Need some advice on how to remove or if I need to replace. Two years old and I do not have a receipt, or box for the product.

Rated 1 out of 5 by from Poor choice We purchased this de-icer 5 years ago and needed Tetra to replace it twice already. We are on our 3rd unit which worked again no more than 2 winters. We replaced it now with a simple de-icer from Farm Innovators that is designed for horse water buckets. I attached it to a home made float and it works like a charm. Time will tell if it lasts but some reviews report it working for decades! Asking Tetra to replace our old one again would only repeat failure.

I have Koi pond approx. 1300 gal , will this keep a hole in the ice on that size of pond and is it safe for the rubber lining in my pond? Thanks, John

Asked by: jmac
Hi John, The answer to both question is yes. I used one in a 5000 gallon pond for three years with no issues. It is designed for rubber lined ponds, and can keep a hole open regardless of the size of the pond. It works well down to about 0 degrees. Less than that you should keep an eye on the pond as the ice may become so thick as to push it out of the water. BREX

Our pond is already frozen. We just purchased a tetra pond de-icer and it arrived via Amazon How do we install the tetra de-icer since our pond is already frozen ? Thank you

Asked by: Carmelite
You will need to thaw a hole in the ice with hot water, then insert the deicer and plug it in. BREX

My pond is frozen already.  Can I just sit it on top and melt through.  Will it float once melted 

Asked by: Coo coo
We would not recommend that, no. Instead, pour a large pot of hot water on the ice to melt a hole in it, then place the deicer in it. It will keep it open from then on. BREX

This is our second Tetra de-icer - first one lasted one season - got a replacement one Dec 2016 - cold weather has come to area, and we put in the de-icer, but .it is frozen into the ice , in other words it is not melting the ice - what can we do -

Asked by: Lillian
there is no evidence that there is a hole around the heater - in fact the item is frozen into the ice - we leave our pump and waterfall running all year, this pond is well protected against many weather situations - we have checked the electrical outlet, no problem there - but with this item you have no real way of confirming that is actually working - no light etc. We do not have a problem regarding Warranty, our retailer is always helpful - We will be returning this item when he returns from vacation next week - thank you for answering my original e-mail

Put the de icer in fifty gallon pond . The water has become very warm and unit has a very hot underside . Recently purchased and considering getting a replacement. Please advise

Asked by: Dave Min
Thank you for your inquiry about this product. The pond is too small for the unit. We recommend a minimum of 150 square feet of surface area. The black metal box on the underside will always be extremely hot to the touch and should never be touched unless in the water. In a small environment like your 50 gallon pond, the water will be heated to around 70-85 degrees, depending on the outside temperatures. It would be very hard to regulate the temperature in such a small pond, which could cause some stress to the fish. BREX

What temp does this turn off and on?

Asked by: Mel V
When the internal temperature reaches 89.6 it will shut off. It does not read the water temperature, and so may operate even during warm times. It is best to only plug it in when the temps are going to be freezing or colder. BREX
