This pond breather really works. It keeps my pond from totally freezing over in the depth of winter . It works and my gold fish make it thru winter!

So Far So Good. Pond is staying unfrozen and fish seem well. Wish it was available in other colors or black.

I have a fish pond. In the winter when things freeze I use this heating element. It is necessary for the gases to escape from the pond and keeps oxygen flowing along with a pond pump/waterfall. When it is really cold/frozen and it has been in position for a while I change that position to melting through the ice in a different area or just next door to it. Chopping through ice can shock your fish and this prevents that action.

Here in Ohio we’ve had some cold days the last couple of weeks: low teens at night to mid 20’s for the high. The “heater†completely froze over. It’s a small preformed pond where I used the Tetra heater in the past, it did its job until it didn’t. This product was a replacement supposedly for the better, but now completely frozen over. Don’t know if the fish survived, pessimistic. The heater is either overwhelmed/ineffective or just trash.

This is my second pond season with this heater. With the aerators and fairly mild winter last year I didn't have to use it very often. But it did the job. However, with the extremely frigid cold this year, it just couldn't keep a hole open. I actually put in in the pond a couple of days before the weather turned frigid to make sure it worked. The first night when it got down to 5F, I checked the next morning and the center hole was completely frozen, same the next night. It wasn't until the temps got above 20 or so that I could tell the center was ice-free. So just be aware that if you have a really cold snap, don't just plug and forget, but make sure the hole stays open. So yeah, this thing works OK if not too much is asked of it.BTW, if the pond freezes over, DON'T use a drill or blunt instrument to try and break the ice. What worked for me was heating up a kettle to boiling, then pouring over an area where I knew the fish weren't. That opened a good hole for a few hours.

This de-icer has done the job so far this winter here in SW Virginia. My koi loves it and hangs out underneath it. I don't feel any warmth when I put my finger in the water nearby or underneath the de-icer. I think my fish just enjoys being underneath it, possibly because he feels somewhat under cover and protected. So if it is emitting any heat, it is very subtle and not dangerous to my fish. Anyway, the few times that the water garden has iced over this winter, the de-icer has left an area where no ice has formed, doing its job. I did a lot of research before buying a de-icer, and I recommend this item, it has delivered what I wanted in a de-icer. I hope it will last for many years. Being made by Pond Master, it might. I have a Pond Master pump/fountain that is over 20 years old and still going strong. BTW, I unplug the de-icer when the temps are above freezing. Soon I will be putting it away until next winter.

Place on ice in pond. Plug in and forget it. Works exactly as advertised. Also arrived in good time after order was placed.

Keeps the hole in the middle ice free like it says. It will start to clear ice away around it eventually. As long as the hole is ice free I am happy

Unfortunately, we had a very early freeze, and had to install this after the ice was an inch thick. In order to put the pump in the pond, we had to chop some ice away. In the instructions, it indicates that chopping/banging on the ice can possibly kill the fish. The heater is keeping the spot where it is placed thawed. We will see if the fish survive the winter…..we can’t determine if they are still alive bc of the ice cover. Really hoping they didn’t die as a result of our chopping the ice….

Immediately after receiving the heater, I installed it in the pond. It melted the ice and everything was fine the next day. Product did the job; very satisfied

I had originally written a positive review, but the Pondmaster unit has completely failed. About a week ago the center hole started freezing up. Today the unit is frozen in ice, in the centre hole and all around the outside. The unit Pondmaster became unreliable at the time it was required the most. Last night was the coldest night of the year, -25 Celsius / -13 Fahrenheit. If it could give it a no star rating I would have.
