I'm a newbie, and recently I noticed this "cotton" looking "stuff" at night in my pool floating. When I touch it, it seems to dissolve and look "milky"?? I think it's scale....not sure. I have a LaMotte ColorQ 7 on order should be in next week. And I intend in order the pool tester from this website, I convinced the wife she will need to help out since I'm color blind. But see my numbers below......I think these guys are crazy. They told me I have a 23000 gallon pool, but when I use the pool cal I average around 16000-17000.....I mean they told me to add 160 pounds of salt, while my generator registers at 80%. When I opened the pool in the spring my salt level was at 40%....I have slowly brought it to 80%.
Calcium Hardness: 90
I want to thank everyone on here. From being on here last year throughout my pool build (a nightmare), until now finally trying to enjoy the pool, you have all been great! 8)
