My tank is set up with a closed loop through a "dry box" that has just enough room for two bulkheads through the wall leading to two holes in the bottom. Bulkheads are 1.5" and 1" and both have elbows at the end going through the bulkhead in the wall and everything is glued. This box feeds my chiller which flows all the time though chiller compressor is only on in the summer.
Anyway, I have always hated how this works as the return from the chiller is low in the tank and flow is too strong in the immediate area. Return is only an inch or two higher than the sand. Tank is 18 years old and I want to replumb the return to actually come up to the top of the tank and through a Sea Swirl. I think if I can cut the fitting right at the elbow I can replace the bottom bulkhead to accomplish this and just put a plug in the bulkhead through the wall. But I'm not sure how best to actually cut that fitting given the tight quarters. Photos below if they help - it's the one on the far right in the pictures. Suggestions?
