I tested my water last week and everything was perfectly where is needed to be (maintained constant up to my next issue). Then I noticed some stains on the liner and realized it was some kind of metal due to my chewable vitamin C removing some of the stain. I took it to a pool store to see if they knew what type of metal because my TS-100 does not have to capability and they said it was not iron or copper, but could not tell me without spending 30 dollars for the skimmer test packet. Anyway.... So I added 3-4 lbs of Ascorbic Acid, removed the stains ans a few hours later added 2 bottles of metal free. This morning crystal blue water, but noticed some small algae stains on the ladder.
Question is seeing as how my TA and PH lowered and my TC is off as well, is there something wrong with the steps I took to remove the stains. Do I just need to get my levels back up then shock? Or is there something else anyone recommends in order to get my pool swimmable again?
Thanks in advance!!
