Need some help with a used system

[dschnepf]

Just picked up a used 420 acrylic and have quite a bit of cleanup to do! Imagine that, but the biggext dilema that I have is there are two rear overflows and 3 bulkheads per overflow thru the bottom!? Any plumbing suggestions here? And also there is no plumbed return. Any thoughts or help would be appreciatted Thanks

you could use two as drains and one as a return coming over the overflow or bulkhead out of it....

You can get the durso designed returns. on the thrid hole you can add a return to each and lock line them over the over flow. Or cut a notch out of the overflow and let the lockline go thru there.

Some people use penducators to get more flow off the lock line.

It's an open pallet have fun with it. Put in Unions on your equipment and shut offs so you can re plumb later if you don't like it.

4 drains would be nice. You could also use one or two as a closed loop. Have your sump have a holding section and let it pump the closed loop from there. (also make a cool place to do auto water changes)


Just thoughts. Reef I suppose right? HIGH flow
