diy overflow

[Instar]

Hey Tim, you skipped a couple things -- measure twice with micrometers, mark it with chalk, cut with a chainsaw and glue or paint to suit.

If you plan on sitting the mini sump behind the mini bow, I can't see where the durso will do much for anything. If you plan for it under a cabinet, then when the pipe is verticle and the durso is adjusted correctly (calibrated some call it), then it will be perfectly quiet and will not get air locked on you causing a mini flood.

You can use a dremel and trim the elbow down if it is too big. I built an overflow for my 40g that turned out pretty well.

It consisted of a 3" T fitting, reduced to 1" to fit the bulkhead. I cut strainer slots on one side of the T and capped the other side. So, strainer up, cap down...in the tank. I then trimmed a 90 degree elbow to fit inside the T fitting and pointed it down like a durso. A small hole for air in the top of the elbow and it works great.

Sorry, no pics right now.

I used a regular hand drill when I drilled mine. Just had to make sure I made no sudden moves. Oh yeah, I tested the drill bit on a peice of glass the first time, and I broke that one. It was 1/8" and I think it did not withstand the preasure. I tried it a gain and was able to drill it by not pushing too hard. It took about 10 min just to drill it. The main thing is to keep it cool. I found that submerging it in water as you drill is the best way. The thing you want to watch for is the last bit right before you break through. Make sure you don't slip and hit the glass with the body of the drill as it goes through. Good luck

I have drilled a couple of tanks with a dremel and the diamond tipped bits. Turned out ok. Do a search on reefcentral for more info.
