Leaks...Around Overflow
Leaks...Around Overflow
After plumbing in the closed loop today, quickly discovered that the overflow box is leaking. The tank has 1.5 fittings glued in (Weld-On) my guess and then has had a layer of epoxy poured into the overflow box that makes about a 1/4" thick epoxy covering which I would guess was insurance for leaks. The epoxy (I'd assume this is what it is) has some cracks in it and a few of the fittings are dripping really fast between the acrylic and the fitting.
That being said, I'm looking to solutions...And think my options are limited to be honest. If I could do it over again I would just buy a new tank but I'm past that point and think I'm best off fixing the leak around the fittings. I believe the tank being in storage might have heated up some and the epoxy shrank/cracked some, which allowed the water to escape between the fittings and acrylic.
My ideal solution would be to try to scrape all the epoxy out, drill out holes bigger, and put SCH 80 bulkheads in place but due to the spacing, is not possible. I cannot just pop the fittings out either as they are held in place with weld on....
My solution at this point is to use Weld-On #16, put around the fittings on the bottomside of the tank, and buy some epoxy and pour it into place in the overflow box so it is about 1/2-3/4" thick. (I've never worked with epoxy and would like to get one that's reef safe, becomes very hard, and is resistant to cracking and sw over a long period of time)
Below are some pictures and would appreciate some feedback if you have any on the subject.

Drying now.....Ready for a solution that I'm ready to implement ASAP!
