Just recently won a long, drawn-out algae battle, and am ready to make the leap to the TFP method - so I don't have to fight that battle again. Full results from my new TF-100 test kit:
FAC: .5 or less
CC : .5 or less
This is all pretty well in line with results from my last visit to the pool shop, with the exception of the calcium hardness. My result is more than double theirs; maybe I botched that test? Unfortunately, the last step in the algae battle (with the pool shop), was a copper algaecide. Shop test results show .9ppm copper remaining.
So here's the big question: I'd love to start my first SLAM tonight, but I'm concerned about the copper level. Pool shop has always been very scary about shocking when I have Cu in there. Slam away, or deal with Cu first? Liner is vinyl - does that relieve some Cu/Cl concern?
Thanks in advance; I plan to be a regular here!
