im having problems with red slime in my tank. its a 30 gallon with a bakpak 2 protein skimmer, fluval 204 canister filter, a current satellite 96w light
specific gravity is 1.020 and i dont know any thing else except temp (ran out of test supplies and have been procrastinating to get some-and just order some via that fish place)
also, a mysterious disease swept through my tank, killing my tomato clown dwarf zebra lionfish and royal gramma
the tank has been up and running for about a year and a half and its current inhabitants include 2 blue legged hermit crabs, a cluster of about 20-25 small feather dusters and two mushroom polyps(red slime hit my corals pretty hard)
i try to clean the slime everyday and reduced the time the light is on from 9 hrs to 7hrs with no results(i dont want to reduce the time anymore, thus depriving my two polyps of photosynthesis)
as for the disease, it looked like ich, but the medication didnt affect it at all(took coral out to medicate)
would a uv sterilizer work to reduce future outbreaks of this mysterious disease??
any replies would be greatly appreciated
