Made a PVC skeleton to support the cement for my own rock structure. Dealing with this narrow tall tank finding natural rocks to even work with this tank would be near impossible. The valves are the tentative placement for the closed loop system, the middle blue one is going to be a drain with two returns on the side of the rock work.
