Well finally got my first corals in my six month old 20G tall tank. Not to long ago I added to much beneficial bacteria which created a bloom and fungus. Cleared it up by water blowing all the fungus of the rocks and a few large water changes. I also added a UVS which I will remove shortly. I am using a Seachem Tidal 35 water filter with polyifil, Seachem Matrix Carbon, and Seachem Purigen. I have a heater and four power heads that provides good circulation. I have two Coralife Marine Clip On lights that are 50 par down to 12 inches. I am reading good reports on soft and LPS corals with these lights. I really like the simplicity of these lights. So I am going to wait and see how my corals do with them. I have a feather duster, fire fish, Chinese zebra goby, green chromis, and luckily a friendly strawberry dottyback. I lost a yellow wrasse, which I should not have put in the tank. I also lost a molly and my first chromis was croaked by a tomato clown fish. I returned the clown fish.
