Hello, I have a 90Gal tank with two Clowns, Cleaner Shrimp, and couple of snails and crabs. I use lava rock so far for aquascape but would like to upgrade to live rock. How do I do this? I have a 10Gal Q-tank that I could use for curing but limited to how much at a time. I would like to keep it open somewhat for lots of swimming room. What do I need to know about buying and selecting live rock. I am looking for a good skimmer, anyone have a used one for sale? Thanks for any advice Marcus.
