Help!

You guys have inspired me to build my own built-in overflow. But I need some help, PLEASE.

 

I have a 40G reef that I was going to sell & buy one with a b/in o/f but it's over $200. So I thought I might build one myself. I hate my external one so I think this is the best way. I'm going to do this either on my 40G or 29G acrylic, not sure which one yet.

 

I know how one works, but I'm wondering if you guys can help me with any hazards to look out for. My tanks are clear with a black back. Is it as easy as just buying 1/4" acrylic pieces, cutting them to shape, seeming them together, then using a dremel to notch the top? All before I seem it all to my tank? I figured I'd drill two holes in the bottom of my tank for to & from my sump/fuge. Or can I buy a 90 degree acrylic piece from an acrylic or Home Depot type store, cut to fit, notch top then seal?

 

Then I figured I'd put in some sort of Durso standpipe for drainage, and a bulkhead also inside the o/f unit for a return. Drill a hole on

 

The tank is a Clear For Life acrylic, and I'm not sure if there are any things I need to keep in mind when drilling these holes, like space between or distance from sides or even if the tank bottom will give out!!

 

If I did the 40G, I figured I'd go 5" lengwise & 3" deep. The tank itself is 36" long & 15" deep.

 

What do you guys think? Is this too difficult or should I just buy a new tank. The tank itself is only a year old so I'd hate to blow another couple hundred.

 

Thanks!

I only have the return in mine but you are right on track with just getting a couple pieces of 1/4" and welding them together. As far as supply for the tank if youre redoing it all why not make a spray bar with clear acrylic tubing?

Use the compact version of the durso located here http://www.rl180reef.com/pages/standpipe/s...en_stockman.htm that way you can keep overflow chamber size to a minimum.

I think the structural integrity would be fine just keep it about 2" from each side. You could probably ask a local glass shop about it just to make sure.

If I did the 40G, I figured I'd go 5" lengwise & 3" deep.  The tank itself is 36" long & 15" deep.

Good size for what you have planned just make sure it can accomodate the stand pipe before you build it.
