SW - Water Change - Need Help

[TVR]

Well,
First of all, thanks everyone for your help.
Second, thereason I haven't done any water change because according to some of my reading, with my tank size (about 200 total or more), should take afew month to have it cycled. Eventough it looked cleared and "sound like cycled now, but I am not so sure about. Even though I do have some invert, 2 clown and very a few soft corals and they are doing ok inthere, but still, not so sure.
I started mixed the soft in the 29G lastweek and get powerhead_heater running, I can do water change anytime now. Thanks for your helps.
Oh, about the green HA stuff. Thanks heaven that my Cerith snails (I have about 10-15 now) they are eating those like crazy. But I do ahve to set them "back to their feet" quite offen since those cuties keep get "out of track" and climb onto glass... So after reading an article about cerith, I tried to "put" them onto those Mr. Hairy and I can see a significant change - Not much yet since I just started "re-possition" them from yesterday, but looklike I found a way out of those urgly hairy stuff.

Thanks guy.
I'll do what you told me right away: Water change and skimming.

Man, have admit that I love this site - BIG HELP !!!
