How do I know what size water pump to use to get circulation in my tank? I have a 125gallon 6ft tank... I cannot find a chart or anything. I don't want my discus flying against the glass, but I want to be sure the water circulates especially around and behind my 3D background... Was thinking about getting a Koralia evolution 1050. Is that ok, too strong too light? Any help?
