Rec'd Ben's test kit today- the one for salt. Took only one week!
Anyway I had a cloudy problem. I also have a small mustard algae problem. I have listened to everyone on the forum and it all helps. Went through a lot of bleach!!!! Well per my kit today my chlorine is at 22.5 and my CC is at 0. I know my cl will come down with the hot sun, but does the CC normally remain constant" ie, if I go down to 3 should my cc stay 0? What causes the change?(cc change) Also how long should it take to come down?
30,000 gal SWG, vinyl pool... 82 degrees. Water is much clearer now, however the pesky mustard algae still comes back every couple of hours or so to the same locations. My pool gets full sun all day. I did add Yellow Treat 2 days ago. It has brought the amount down, but not to where it is 0. I am going to find Yellow Out and try. Cl did nothing- look at my number- it has been over 15 for days. CYA about 28.

Thanks
