heaters

Lack of water changes. As a kid my parents did tell me to do water changes on my tank, but I never kept up with them. Even though I didn't test the water, I'm assuming my early fish deaths were from bad water quality, because when the weak fish were moved to new water to monitor them in, they...

I heard that heaters could break easily, but mine has a 15-year guarantee so I'm not too worried about it. It has the temperature on it but that can be a little hard to read, so I have a stick-on external temperature marker. Idk what else I'd use. The heater lights up when warming up the water.

I have a 110 gallon tank that I'm currently trying to heat but while I was looking for one to buy I kept getting varied reviews. What would be the best heater for me to buy for my tank, on both accuracy and temperature control.

Hey, I'm going to upgrade from a ten gallon tank to a 29 gallon tank and I was wondering if I could use both the 10 gallon heater and the 29 gallon heater in the new tank. Both of the heaters are used so I guess they might take the strain off of each other. Or, would they make the tank too hot...

My 15 gallon seems to be hold up at 80 degrees. I don't know what brand the heater is but it is a submersible. Seems to work great but I wonder if 80 is too much for a tropical tank?   Then my 10 gallon has a tetra whisper heater 5-15. The tank has been sticking around 77.9 - 78. Would that be...

Hi there First post so here goes. Just bought a new and my first external filter (fluval 406) for my juwel rio 180 as its the only one that seems to fit in the cupboard, and was wondering if it was a good idea to buy an external heater to go on to it? Thanks a lot Rob :)
