Mine is awfull... I can't win, and have no idea what's up!
It's dark maroon and if I allow it to grow it gets long strands (hair? Filament?)... it is smothering my live rock, where I clean it off the LR
is bleached white, ugh. I've got some ideas about what might be causing but I can't get it to stop... the crabs won't touch it, my lawnmower blennie doesn't want anything to do with it, in fact the only thing I've seen eat it was a cerith snail that went up a tank wall and left a trail...
I'm not skimming (new tank, old skimmer no longer works, I'm buying a new one this week) but the growth so fast and huge (long strands, covering everything in 3 days) that I don't expect that a skimmer would help a lot... I did a 30% water change with no noticeable change in growth rate. All the fish/crabs are doing fine, no corals/anemonies yet... I want to figure this out before I start killing stuff!
The water I use is from the Natural Foods Co-op, I checked with the vendor and they assure me that it's reverse osmosis, and filtered... I tested it myself for Nitrates and they are 0, but... could this be silicon? Or, phosphate? I don't have a test for those yet. (maybe I should, heheh)... I'm going to be really put out if my hippie water is made by liars!!!
Anyway, any help would be greatly appreciated... this has been the easiest set up I've ever done (0 ammonia within 2 weeks, 0 nitrate within 3 weeks, GASP) but now, suddenly it's the late night horror show we all fear!!!
