Great page! Looks like it's the K-1721 for me; I will definitely purchase it for next year.

Unfortunately, I really think my pool is "toast" for the rest of the season. I'm stirring and wiping and filtering, and still have (slightly) cloudy water with dabs of algae here and there. It has significantly cleared up, but with all that chlorine in the mix I can hardly believe that any algae is hanging around. Chlorine only went down to 45ppm since yesterday. Maybe I have way too much stabilizer in the water? I'm just really tired and I miss floating in my pool and watching the clouds go by - lol

We'll see what happens by Monday or Tuesday. If things don't change, I'm going to make a tarp out of it! Thanks for all the help though, I really appreciate it.
