What are your thoughts on bio balls. I am getting a sump that has them. I am debating on using them, mixing half with live rock rubble or just using a'll live rock in the sump. Also where can I find out fish aggressiveness compared to others. Doing a fowlr tank and looking at tangs,triggers, puffers, angels and clowns.
