I'm using RO (always have) but I just saw another thread
here that sounds like what I may have, Cyanos. I just did a search and found an
article that seems to explain what to do. I tried e-mailing the author but the email is no longer valid. Below is what I said, any help would be appreciated.
"Albert,
I just came across your article because it sounds like this is the algae I
have. It is very slimy and draping out of the power filter returns. It is
basically dark green but has red within it. Mostly, it has blanketed my sand
bed and all the rocks. I can siphon it off but it returns very quickly. All
of this sounds like your description in the article on Cyanos. I haven't
looked to see if there are any feeding guides, but almost all the food I
feed them are of the frozen cube type. I feed the animals every other day. I
don't have a large cleaning crew, snails and hermit crabs, perhaps 3 or 4 of
each. I also have several dead spots as far as water movement and my skimmer
isn't of the best quality. From what I've read, until I fix some of these
problems it will be a losing battle. Besides upgrading the skimmer, how
important is water movement, feeding, and my cleanup crew size?"
I plan to fix my water flow problem anyway, but it sounds like a skimmer upgrade may be a good idea as well.
