Well I started off with a green pool. It is now in swimming condition. However, the FC levels will drop 4-5 ppm per day. I don't think its sunlight doing the damage because my CYA is fairly high. Any suggestions?
FC 1.5 (but I just added more)
Also, I have noticed that some of the return 'eyeballs' in my pool aren't aimed for the best circulation. Mainly the one closest to the skimmer. It's aimed towards the surface which knocks all of the floating stuff away away from the skimmer. So I tried to aim it down lower and it seems pretty well stuck. From what I've found here and other places on the web, they should be pretty easy to adjust. Just wondering if anybody can offer some advice on how to adjust and/or replace these returns. Here are some pictures, the second one has some tabs that look like a special tool is used to turn it and 2 of the 3 returns in my pool have those tabs.
