hello again. i hate to bother you but since i have added the pool stain treat, until yesterday, my water has been clear. My chlorine level has not been showing on my test kit. bought a different kind and it was showing FC at 1. I was using 3" chlorine tab in floater. I was happy with that since my water was clear. My husband decided to listen to someone at work about if our chlorine was low we could have bacteria and all get sick. Without me knowing he added shock, then the next day chlorine granules to our pool. I have no clue how much. Needless to say, brown water again. I took my water to get tested since the colors that showed on my strips didn't match some of the colors on the container.
pH 8
FC 5.1
TC 5.1
Alk 140
CYA 60
Copper 0.13
Iron 0.17(was 0.9 last time got it tested)
Hardness 140
Phosphate 300

My question is that if my Iron level is 0.17 would that be the cause of my brown water or something else? My water is the darkest it has ever been, but i'm assuming that's b/c my chlorine level and pH is the highest it's ever been, right? Also, I did add calcium. The pool store told me that i should add it b/c they told me that over time being low my liner could become brittle. They told me to add 2Lbs for my 5000gals. I don't even think I added a pound b/c i wanted to go slow with that. Could that have added to the brown, also? I was doing so good. I kept my pH at 7.2 and chlorine at 1 with that floater. I have never added any more cya to my water since i setup my pool. Why did my pH rise to 8, and cya go up to 60 since he added the shock and chlorine? The only cya i added was when i opened my pool a month ago, and my shock or chlorine does not contain anything like that.I did add the pool stain treat again last night. I guess since my water is real dark it will take longer to clear? Also, I know this could bring my pH down. If it doesn't bring it back close to 7.2 how long should I wait before I buy something to bring it down?
