bulkheads in plywood tank
I am in the process of building a 180 gallon plywood and glass tank. I have built these in the past and had good success with them, however, with this tank being much larger than previous tanks, I am planning on using a wet/dry trickle w/ a sump. I am curious if anyone has any experience drilling and installing a bulkhead in the bottom of one of these tanks. Obviously, the drilling is simple, but I wonder about the bulkhead. Will it seal properly against the epoxy? Or should I silicone a drilled piece of plexiglass around the hole to seal it better? Because of the tanks location, an overflow w/ external stand pipe is not going to be an option. That is why I am planning on the internal stand pipe.

Nick Wise I have never had a problem with bulkheads in my plywood grow-out tanks. After drilling the holes however, I always coated the exposed wood with a couple of coats of epoxy. Tom |

Nick Wise Nick Wise http://members.aol.com/nwwise01 Hey Nick, You are ok, aquarium silicone on all 4 surfaces (enough to squeeze out of the gasket when you tighten it) then use your finger to spread a nice seal from the excess. Never underestimate the power of silicone. You may want to rough up the epoxy around the holes with some sandpaper to help adhesion. I have found that the most common problem with leaky bulkheads in any type aquarium is due to over tightening of the bulkheads which deforms the gasket. Otherwise they are more reliable than you would think although they do age and after 5 years often start to seep and leak. That's why I use the silicone. It will seal the glass and the ply well too.
