Archerfish
Fish Crazy
Agree. I used a Hydor 300W inline coupled to a Marineland canister for many years on my Archerfish tank and the system performed flawlessly.Of all the heaters brands I have owned the one I favor is the Hydor inline heater. I have them on the three tanks where I use canister filters. It took almost 20 years for the first one to fail. I had a replacement on the shelf for years.
