I like to know what size powerhead I need for my 3'X2'X20" tank. Currently it has trickle filter system with water in take and outtake at the top of the tank. It's connected to Eheim pump 1250ltr/hour.
It's hardly have any water movement at the bottom. I know I need to install a powerhead at the botton of the tank to increase the circulation.
What I like to know is what size of pump I need. Will 2000ltrs/hour too much?
Again Akoh can you comment?
