Steve this is a little of topic but I have a 20h gallon and I place my power head way up about an inch away from the black rim because I had it about halfway and my fish started to fade and not be as active so I figured they were swimming to hard. My PH
is 152 gph
do you think this is appropiate for my size of tank 20h gal
. and what do you think about the positioning of it.
