I was recently given to Cool works ice probes. Normally I have my big tank running on a big chiller. So I've never used ice probe before. Or seen anyone else with one. here's what I think.
One of them had a bad power supply so I had to order a power supply. When I shook the power supply not the cord but the power supply it turned on and off. I'm not impressed that the power supply is 50 some bucks which is half the price of buying a new unit. But I did it anyway.
The reason I went ahead and did it is because one it's working it's working really well. When we had 90 some degree weather. My tank stayed at 79. I put it on my husband's lagoon 25 gallon one of them. And the other one on my 10 gallon baby clownfish tank. I will have pictures below.
The units don't have controllers to them so they would constantly run but I have an ink bird controllers on all my tanks so I just went ahead and plugged it into that and it's a plug and play. So it turns on when needed. They make almost no noise just the fan going. I went ahead and installed mine into the egg crate on top of my aquarium instead of drilling my aquariums because they're already running. And I didn't want to waste room in my filters. This actually worked really well. In my one the egg crate is in my overflow. It seems to drop both my tanks down equally about a couple degrees. I'm sure it could drop them more, but my controller turns them off by then. It's not as fast as my chiller would be at dropping down but I have that adjusted in my controller so it turns on sooner.
I do like the fact that it's energy efficient a lot cheaper to run than my chillers and my other tanks. I don't have to add ice bottles Everytime my controller alarm goes off. Mind you that's slot. My tanks are all in the garage.
All in all it was a gift given to me. And I know they're a little over $100 each normally at the store so I'm very happy. I await 105° temperature this weekend.
I'd give them for price and smaller tank size usage a 5*
