Lol I will post my readings when I get home but here's my story.
3 weeks ago I went into pool store with a crystal clear pool. My only problem was what I'm thinking is dead algae on bottom of pool. They tested pool and said calcium was low. Bought and put in 25lbs of calcium. Pool guy also suggested and we bought this "pro magic phos free" system. One bottle to start up and then a maintenance bottle which you add 2 1/2 capfuls every week. Supposed to be guaranteed algae free or they GIVE you the chemicals to clear your pool. We vacuumed pool several times to waste. 2 weeks ago we went back to pool store bc we had a yellowish tint on bottom of pool and on steps (we never got dead algae out, it will not vacuum up) but water was still crystal clear. He GAVE us a bottle of copper algaecide bc we were on this phos free program and sold us a bag of cellulose fiber to put in our sand pump to help trap the small particles. Our pool went from crystal clear to you cannot see the bottom at all and we still have yellow on our steps and bottom of our pool. We did add 6oz of copper algaecide in the pool which I regret now after reading. After reading skme forums I added 4lbs of shock since Sunday. Pool is starting to clear but we still have the dirty look with yellow tint on bottom and steps.
The pool is a 28x52 round vinyl pool ag
Pump is sand filter sparco with a optiflo and it's the larger pump than what normally comes with the 24ft pools. I will post my chemical readings as soon as I get home. I did go and buy a drop test kit and did that last night and iffy number don't make sense I apologize. I am very very new to this. Thank you so very much
