Mag 12 big enough for multiple tanks?

Ding2daDong · 11/29/2007, 09:25 PM

I am setting up a system where my sump and 2 frag tanks will be in the garage and my main display will be plumbed through the wall.

The pump I have and plan on using is a mag 12 to Tee the return to all 3 tanks. The two frag tanks are 30g breeders and the main display is a 75g aga. Just wondering your thoughts before I spend all the money on plumbing parts to realize it is not enough flow.

Any help would be greatly appreciated

Thanks

well, the mag 12 does something like 1200 gph right? divide that by 3 and you have a max of 400 gph going to each tank. when you account for head loss and plumbing, it's probably a lot less than that. how far apart are the tanks from each other?

i run 2 90's and a 40 off a mag12, and even if its not enough flow, the plumbing work would virtaully be the same, you would just use a bigger pump.

I agree, after all the plumbing head loss etc you wont be happy with flow. You have to remember turnover in each tank as well and factor that in.
