I am planning a 240 gallon display tank (72" long x 30" front to back) and wanted a generous-sized sump to fill that space below.
I saw a used 100 gallon acrylic tank (48" x 22" x 22") and jumped on it, but there's a complication. It's a reef-ready tank, so there are corner overflows. I thought either I could remove the overflows or just cap the bulkheads and leave them there. No big deal to give up space in the corners.
But I just learned that the overflows are not watertight. If you fill either overflow while the rest of the tank is dry, you can see water streaming straight into the tank. So they will get stagnant water, which I don't want. Do I try to seal the seams? That's 21" x 2 sides x 2 overflows, plus the width (5"?) x 2 x 2. If so, do I get some Weldon #60?
Or do I try to cut them out? I have a dremel, but am not very handy. What attachment do I use and what am I in for? This sounds scary to me as I will probably make a mess of it.
Thanks!
