I have a custom built 150 gallon sump with bubble traps for sale or trade, Was going to use it for my twin 180 set up but had to change the stand design for better structural integrity. Thus the sump is too large for that application.
150 for the sump. Its predrilled on the side two 1.5 inch holes and one 1 inch hole. Has a refugium and four bubble traps, designed it for a high flow sps system.
