Overflow box for Durso Standpipe help..

sonoranaut · 02/01/2007, 09:05 PM

Aquarium to be built: 48'x24'x24' w/ left corner overflow box

I would like to have 2 holes made in the bottom of the overflow box for the following...

1) 1Â½" bulkhead with a Durso style standpipe
2) Â¾" bulkhead for sump pump return

What should the dimensions of the overflow box be to accommodate
the two holes mentioned with one having a Durso attached to it?

6"x6" is the standard I believe and this would be to small, wouldn't it?

I'm thinking 8"x8" might do it?

What size overflow do all you Durso owners use?

Thanks in advance,
Mark

Well given the tank is approximately 120 gallons... Given the 3-5 times turn over rate... 600 gallons max roughly.... The 1.5" drain would work with a minimum of 9" linear over flow... So yes 6"X6" would work... Just for ease of install though I might go 6"X8"... It would give you 2 extra inches to maneuver the plumbing around inside
