OK, pool is all clear. I would have never known that that was alge, I always think of green slimy stuff. I guess it could have gotten that bad if it had gone untreated. This site has saved me lots of $$$ since I bought this pool last year. Ijust received Ben's kit yesterday, just wish the CH. tester went higher it's the same as the 5-way from walmart (only goes to 5). Just have to do the dillution or do a partial drain.
Thanks again for this site and all the help. You guys are good.
