rate on the tank ill he able to figure out my turn over better. Make sense?
Water turn over is different from filter rate. Basically your turn over is filter GPH
(return pump) PLUS the combined flow of your powerheads. Like in my 210, i pump 1800GPH through my sump with a mag 24 return pump but then i have 6000 GPH
from 4 koralia 1500 powerheads in the display tank. So my tank in no way could drain 7800 GPH
but the turnover in my tank ends up at 37X per hour.
