so last night I posted pics of my crystal clear pool water. So then late last night I brushed down pool and vacuumed as usual then back washed and rinsed filter. I put my solar cover on and added water to my pool as my level was starting to get low. I was all excited as my TF-100 test kit was scheduled to arrive this morning at my house(its actually there now, but i'm at work) This morning when leaving for work my pool was green. I had been using the Walmart test kit while waiting for the real one to show up and everything was kosher(til this morning). these are the things I know about my fill water. I'm on a well so I have alot of Iron and I know I have a high level of manganese in my water which I'm sure is partly the cause to all this. After testing last night and using pool calculator I had to add 222 oz of bleach. Below are the results of the Walmart test kit. everything had been pretty much spot on for the last week the only thing that was changing was the chlorine levels and I was adding as needed.
OTO test = 4
TA = 100
CH = 260
CYA = 40
However, I am not worried as I know I can get it back and I get to use a real test kit tonight (just wish I could skip out of work and get to it) and correct this issue.
