Mike D says:

Any advice is appreciated…. I have about 12 gallons of water inside my 14 gallon all in one clown fish tank (sand, rock, equipment take up rest). I want to make sure I have the correct gph return pump. 12 gallons x 10 would be a max of 120 gph pump… but I also have about 10 inches of head pressure and 1 elbow. I have a circulation pump within display area. I have a nano pump that is 110 gph and is only 2.8 watts. I got this because it is very quiet and doesn’t heat up the tank too much. Everything seems to be good had it for a year at least but should I get a bit more powerful one such as the CompactON 600 (159 GPH) – Eheim, Trying to keep heat and noise to it lowest. Thanks.

SuperScuffle says:

when you say 5x to 10x tank turn over do you mean display only or dislapy plus suimp? I have a 12g fluval edge i am fitting with a 10g custom sump. Do i calculate on 12g (display only) or 22g (display and sump)??

leahfiish says:

What are the issues with using a smaller than recommend pump? Will I be okay as long as I supplement my display with extra powerheads?
I have a 90g with a mag 7 and about 7′ head loss.
