Need help setting up sump...

[kgoldy]

I'm trying to figure out baffle size and placement in my sump... I'm guessing I need to prepare to lose 2 inches out of my display tank when the pumps shut off, plus water that's in the pipes.


40Breeder sump's interior measurements are 35"L x 17.5"W x 15.5"D. = 9493.75 cubic inches available in sump

75 RR Display dimensions are 48"L x 18" x (2" of loss) = 1728 cubic inches of potential flood water

Chamber on the left is for filter sock and skimmer.

Between chamber 1 and 2 is bubble trap. (three baffles)

Middle is return, with two separate pumps. One large for return to display, one small pump to bring water into the fuge at a slow rate.

Between chamber 2 and 3 is a single pane of glass, which will be higher than those on the left to allow fuge to have deeper water than the rest of the sump.

Right chamber is fuge.


I'm thinking the bubble trap glass should be about 10 inches tall by 17 7/16" wide.

Fuge wall on the right will be 17 7/16" wide and 14 1/2" tall.

So, water level should be 10 inches max in chambers one and two... and 14 1/2 inches in chamber three.

Chambers 1 and 2 will be about 9 inches wide, each. Chamber 3 would be about 18 inches wide.

Think I've got enough room for when the pumps shut off? It's getting late and I can't think...

You should have enough for when the pumps shut off. You also have to take into account of the skimmer. The skimmer holds lots of water when its on. When the power goes off, that water will come out of the skimmer. Also, try not to have to many pumps in the sump. To much heat. You can build a small manifold and tap into it for carbon, phos, and calcium reactors etc. You can also redirect some of the flow to the fuge from the manifold. Hope that helps a little.
