Does anybody know what this stuff is and how to get rid of it? It has appeared on everything in the tank. Removed it from the glass and used toothbrush on some of the DIY rocks but not on the live rock. It has been white not green and slimey feeling.
The alkalinity is low and calcium is high. Using reef builder to raise alkalinity.
all other parameters are ok
90 gal, 2-250 MH, 2 VHOactinics NO3 - 0 PO4 - <.1 NO2 - 0
NH4 - 0 PH - 8.2 Ca - 600+ Alk - 0
Sp gravity 1.025 RO/DI with <4ppm TDS
Tank had only been set up 6 weeks and this showed up after 3
By the way I have been listening to the podcast and almost caught up now that I have a MP3 player. They have been very informative. Keep up the good work.
I'm not sure about the white feathery stuff and I can't wait to see the outcome. However your calcium is at 600+ I am assuming 600ppm? If thats the case thats a little high and i would consider bringing it down a little. IMO of course.
If your calcium could reach that high a level.. I would imagine that you had a snow storm and you are seeing precipitation of calcium carbonate. Otherwise *shudder* it looks like hydroids!
i agree dave, it almost looks like bleached out macro algae that is powder coated like from a Ca precip event.
also the Ca that high is because your Alk is so low.. you have your Ca/Alk balance all out of whack, i bet it was a precip (precipitation) event in there

I'm still not sold that this is an algae or not. If you have something that looks like that, but green, it could be common hair algae, or bryopsis. Another, that looks similar, but is a different algae all together is Maiden's Hair.
if it is feathery, and very tiny, it could be bryopsis. If it is feathery, and a larger (macro) algae, it is could be caulerpa taxifolia.
I'm not sure about any one stop source for ID of this kind of thing.. but Renee (SeahorseDreams) is putting some kind of a "What-s-it" post together. Maybe she'll chime in here.
Sarah Lardizabal has a great article in reefkeeping this month on macro algae
including a section on "Dealing with Nuisance Macroalgae"
This section also includes great links and information on how to identify the macro algae in your system
here is a link Beyond the Refugium: A Macroalgae Primer by Sarah Lardizabal - Reefkeeping.com

All that looking and I found out that it is simple hair algea but a different type of hair algea. Anyway there wasnt much so I removed almost all of it, with the understanding that it might be back.
