GPH?

Wow!!! That is an awesome tank! Holy smokes!


As for your initial question, I don't think it is overkill. I run a Water Blaster HY10000 that pumps out 2600GPH for my 180G system. You definitely have to take into account your length of plumbing and # of fittings as T's and 90's greatly reduce your flow rate. I also run my reactors, water change tank and frag tank all off the same pump so my water speed through my sump is greatly dimminished.

For a seperate fuge I would have a very slow flow controlled by a valve. I am of the opinion that whether the flow of water in your sump is greater than or equal to the skimmer pump rating, it doesn't really matter. At the end of the day, the skimmer will do its job but your water might pass it by a couple of times before it gets cleaned up. Still no harm done.

Always found the idea of must have X.XX turn overs an hour or or must exactly match your skimmer intake pump little hard to believe. Where's the harm in having your return pump contributing to the overall flow in the display beyond some value through the sump no one can reach a consensus on?

I can a agree there's more efficient ways to get flow in the display than a return pump and so much through the sump you have to put brackets on the skimmer so it doesn't tip over, but I wouldn't be getting overly worked up about matching a magic flow number.

I have probably 4x turn over through my sump. I carefully calculated this based on the cleanest pump I had in my box of pumps, considering clean was more likely to work. MAG12 won, minus head pressure, plumbing restrictions and sludge inside pipes, I figure 4x. Or 5. Or maybe 3.87658. Basically water falls down, water goes back up.
