Okay here we go....first time post and am determined to control my pool myself! Test results (from pool store yesterday)
PH 7.8 ppm
CH (Hardness?) 375 ppm
CYA 70 ppm
Water continues to look great! Continual problem with mustard algae as well as some emerald-green moss that has appeared on some of the natural limestone border. Have scrubbed with a wire brush and scraped a chlorine tablet on spots a couple times. Have been trying to boost chlorine (have thrown in some Zappit 73 Calcium Hypochlorite Granules a couple times; maybe 3 cups per application) However, the Zappit is probably 3 years old and I have no idea of its' shelf life? I am running my SWG 12 hours a day on 100%. Just cleaned the filters. I bought the recommended test kit but am intimidated by all but the small blue box. I can test the chlorine and ph okay (anyway it appears to agree with "boys" at pool store) and have decided that the salt indicator on the cell ( Intellichlor IC20) itself may not be accurate. (I have been depending on it to tell me when to add salt.) According to the strips that I ordered, I have just now gotten my salt level up to 34000 which is recommended and confirmed by the "boys" at pool store. Is there hope for me?
