Can I see some sumps?

[Kabong]

Here's my draft up

And heres the real thing

[Starry]

Isn't the water in that sump a little high? What happens if the pump turns off?

[Chad]

yeah, that looks like it would flood for sure if the power goes out. You should leave a good 3 or 4" from the top for tank flow back into the sump with power outages. Just the water in the pipes alone will flood that sucker.

[Mikee]

yeah you will want to cut down those baffles. About 3/4 height from tank would be enough this way you will leave lots of space incase of P/O.

[dsaundry]

Agree..Flood probable.

Heres one of mine. This pic was taken before the tank was filled. The skimmer goes in the first chamber, andit certainly isnt this clean anymore

Notice both of you have a dump off the pump to dump right back to sump. Shut off installed tho. Why?

[Kabong]

Oops Should have said that my sump is off in that picture.

The return on the pump with the ball valve enables you to control the GPH that goes into the tank.
If you have too much pump for your overflow or drain to handle, This will allow you to slow it down.
