Ok, I've read that it's good to have cheato in your sump/fuge, so I put some in but now I can't find any info on how to take care of it. Is it ok to take it out and rinse it in some saltwater, I ask because it seems to me that it has collected a lot of gunck on it. It looks like part of it may have died too because I'm seeing a few strands that look white. The first few days that I had it, it did a great job of helping clear up the algae in the DT but now the algae is comeing back. Any suggestions would be appreciated.
