A friend of mine is taking down his reef and is selling his mixed live rock (branch, fiji). He also has a 20gal long AGA aquarium designed as a refugium with a mag 5 pump. The refuge and pump was only used for 3 months-----$75
There is about 100lbs rock. Stix is first in line. The refuge is a 20gal long aga aquarium. It has glass baffles for the return pump and the overflow....its a good fuge design
NO it is not drilled. It is a simple 20gal long AGA with 3 baffles on the intake, refugium space, 3 baffles then the return pump. There is no space for an in sump skimmer
