Where/Wanted to Buy: Internal Overflow Questions

[jeffrey_ropp]

I'd like to replace an existing internal overflow with something smaller.

Currently the overflow measures 6 1/4" x 13 1/2" x 23 1/4". Its just too big of a footprint for my 110.

Currently there are three drilled holes (2x1" bulkheads, 1x2" bulkhead) in the following arrangment:

Since I want a durso standpipe, I'm thinking that I could convert the 2" for a 1 1/2" version.

Plus I could use the hole on the right for a return. The left hole would be capped.

Does this approach make sense? Other ideas?

Where should I buy one?

Many thanks!
Jeff

Not sure I understand how that overflow works. It is supposed to be internal, but there is a bottom piece on that box? Shoudn't the bottom part be open to connect to the bottom of the tank?

antiant - Not quite my size. Thanks anyway.

silverarrow27 - Thanks...I'll give them a call.

bennyinca - You guessed correctly. There are matching holes on the tank floor.

<b>I do not want to keep the overflow pictured. It just illustrates where the holes have been drilled.</b>

Anyone familiar with these guys? http://www.wetdryfilter.com/internal_overflow_boxes.htm

I'm now thinking that the best approach would be to drill another hole next to the large hole (that way the overflow can remain in the center of the tank. Something like this:

<img src=http://www.zoyzoy.com/aquarium/reefcentral/largeoverflow2.jpg>

Red= Capped
Green = New Return (1" bulkhead)
Blue = Drain (2" bulkhead reduced to 1 1/2" for durso standpipe and spa-flex to sump)

White = Outline of Old Overflow
Yellow = Outline of New Overflow (about 7" wide x 6" deep)

The spaflex (or an elbow) would have to turn 90 degrees immediately to traverse over to the filter sock. Will that work?
