Pond liner refugium?
My husband has more fun with the refugium and wants to expand it. He wants to build a box of wood, well sanded with all rough edges gone. Then he wants to line it with pond liner, the heavy black plastic stuff. The area he wants to put it is an unusual shape and no traditional tank of about 20-30 gallons will fit. It is obviously fish safe but do you all think this will work? We have seen above ground pond made of wood so a well built structure should hold. What are your thoughts?
72 gallon bow front, koralia 1 powerhead, approx 30 gallon sump and separate 20 gallon display refugium, Aqua C protein skimmer, Live rubble filteration, 80 # of LR, and a 4 inch sand bed.
