Just had a 16'x33' vinyl "sport" pool installed. Enjoyed 1 swim on the evening of the 4th then the clouds opened up. Mud runoff into the pool even though the retaining wall was holding most of it back. But it was a true gully washer.
So that is the reason I found your site. Did some maintenance, vacuumed to waste, filled up pool, lots of shock, going to re vacuum today even though it doesn't appear to need it....all because of your site (I can see the drains again)!
After having those results I decided to join. I will update my profile when I have time. Ordering the TF-100 tonight after work. When I get the kit and do my first test ill post results and ask for some feedback.
