Hey Dan, I have found that diatom filtration for a day will clear up the water just fine. You might have to do it a couple of times, but it works great. -----Original Message----- From: Simon, Dan [mailto:dan.simon@pcgw.claircom.com] Sent: Tuesday, December 05, 2000 8:34 AM To: 'GSAS Mailing' Subject: In need of UV All, Help. I am temporarily in need of a UV sterilizer to combat a green water issue. If someone has one to loan for a week (or so), I will return the favor with some of the best Rainbowfish you've ever seen.
