Add internal overflow

[John08007]

I have an undrilled 180g that I wanna drill. I was originally planning on adding one of the ghost type external overflows but am now reconsidering it. The tank will be up against a wall making it impossible to ever remove the overflow or bulkheads without emptying the tank. Now I'm thinking about having some 1/2" glass cut to make an overflow inside center back. My idea is to come out say 4", across 8-10" and then back 4", this will allow me to have 3 bulkheads. Thinking if I make the front piece about 2" shorter I can then make a black plexi u shape to fit around the glass with a weir at the top. I feel it would be better to make the overflow out of glass because of the silicone bond vs plastic-glass. Never understood how they attach those abs overflows.

Anyone ever do anything similar? Pics, suggestions?

Hasn't anyone added an internal overflow?

Few things out there. Thinking about doing the same except to make an external refugium.

I didn't even think of drilling the back top like that instead of the bottom. Just not sure about the plastic-glass bond, I think I'd use glass to construct it with a plenty cover with a Weir

Why would you ever need to remove the bulkheads with the tank running?

I get accessing the standpipes, but the bulkheads should stay in place.

99.9% of the time if it is a tank with any size to it, the bottom is going to be tempered.

silicone is not the best stick but i thin sikaflex polyurethane will stick the acrylic to glass better.
