Had a tank made with a hole drilled in the back corner for a bulkhead fitting. I should have requested the mfg make the internal overflow box for the tank, but I didn't.
I planned on siliconing two panes of glass in a l-shape and siliconing the contraption to the corner of the tank. Problem is, the euro bracing on top does not allow me to reach down and properly silicone the edges of the L-shaped box for a leak proof design. As well the silicone on the edges of the bottom of the tank leaves a lip so the edge of the overflow can't butt up tight against the tank walls.
I do have a 4 sided acrylic overflow box with a full bottom. I was thinking of drilling a hole in the bottom of the box and running the bulkhead through the box like this
bulkhead fitting ->gasket->overflow box->tank bottom - > bulkhead nut
I could use a thin layer of silicone or Marine goop between the overflow box and the tank bottom to ensure water can't seap between the two.
I have done this in a previous tank, but the tank is now leaking. I can't tell if it's leaking through the bulkhead fitting but it could be a likely source.
I am not entrirely confident that the silicone or Marine goop will adequarely seal the bottom of the box and the tank bottom. If the sealeant should fail, water could seap between the overflow box and tank bottom working around the threads of the bulkhead fitting and down through the nut.
Any suggestions or am I just being paranoid.
