Flourescent Green algea???

[jwoyshnar]

Hello all, since my little issues a week or so ago with the coral shrinking and my maroon clown dying i have had an algea issue. The stuff is bright green, almost if it not flourescent. It is very hard to get off the glass. The usual magnetic scraper has a heck of a time with it. It soulds as if im using sandpaper on the glass. Any ideas? Could this pose a problem?
thanks

Sounds like green coralline algae

What are params?
Using RO/DI?
Regular WC's?
How old tank?
Lights?
Not impossible, but coraline wouldn't be my first guess.

I know the stuff you are talking about...its worse than scraping coraline! Usually when you get that kind of algae it's because you have excess organics in the water. I would do a rather large water change and scrape the algae with a razor blade. When you scrape it have a micron filter running to catch all of the algae and it should slow down it's growth a good bit. The algae isn't the problem it's a sign that water quality is poor. I have battled that crap before.

Hello, all parameters are good. Ph 8.4. ammonia-0 nitrates and nitrites 0 Salinity is .024. I was using well water but for the last water change i used Ro. I just changed 12 galons out of the 55 a few days ago and did 10 last week. My anemones(RTB and Atlantic) seem to be thriving now(not that they werent before but they seem to be doing better). The RTB has never been bigger. Thing of it is i have 2 55's running. The one in my bedroom has the issue. The one in the livingroom is doing great. Same water, same changes. T5 lighting in living room, powercompact in bedroom.
Thanks

Agree w/ the nutrient comment.
Have you tested water for TDS?
Are the PC's old?
Skimmers?

Maybe the pc's is the problem... my 29 has pcs and grows this crap but my 90 has t5's and it doesn't grow. Hmmmm.....
