Is a 100watt heater ok for a 29 gallon tank? It will be in the basement so its cool but still heated. It's fully submergable so I can set it horizontal across the tank if that helps.
Then what size would I use for a 56 column if I used 2?Having two smaller heaters is better than one in my opinion. If you had a bigger heater for your tank and had a electrical problem with it then it could fry your fish. Having two smaller ones would also give you a backup in case something was to happen to one of them.
ok thanks! I will definetly look into that!Not sure for a column tank. But as for an example if it takes a 200w heater to heat your tank then you would just get two 100w heaters.
