well i just pulled off as much of the green stuff that i could, then i cleaned my cyclone back pack and filter. Then i put a phosphate(sp) remover in the filter. I also went and got 15 gallons of RO water and mixed up some salt so i can do a water change in a few days. I have 29 gallon tank with 40 pounds of live rock and 20 pounds of live sand, one backpack, powerhead and filter and power compack lights. I have one clown fish, hawk, damsel, and a royal grommie. The only corals i have are some polips, and one coral that is red and branchy (i have no idea). The thing is, the red coral double in size in about three months and i don't add anything to the tank accept water changes, everything else looks super healthy and i never have any problems except that green stuff that grows all over everything.
I called a pet shop (Scotts) and the guy told me that if its this certain type of algea then there is nothing i can do because it grows from the rock?!? He told me to get a Kole tang because it will eat a lot of it.
P.S. i ordered 20 turbo snail and 15 crabs from reef keepers and almost all of them died, so i ordered more and most of them died again. One thing that i did notice is that there are about a billion white star fish and baby turbo snails in my tank.
Sorry such a long post and thanks for all the help.
