its great you already removed the bio balls from the sump. these ( and any canister/hang on filters, even filter socks, filter floss/sponges tend to trap debris causing excess nutrient build up.
the clowns are just protecting its territory.
Well, I have an update. So, I went to the LFS today, and I think the fish guy talked me into getting a pulsing xenia. These soft corals are very cool. LFS guy told me they would work with my current lighting conditions, and not require any major modifications to the maintainence schedule. What impact would adding this soft coral to my FOWLR tank? Will it kill my filtering algae? Will I have to modify my filtration? Will iodine or anything else need to supplement his care?
Also, it was recommended that I add carbon to the system. Do I add one of the carbon filtration bags, get a new carbon filter "sheet" or get the activated carbon crystals? How many do I add?
