We completed our new pool last August and having no knowledge of basics just did what the pool store said. We recently got stains and they gave us a quart of Metal Miracle on 4/15 and said it would take a few weeks to clear up the stains. I found this site and started reading it. We purchased a Leslies DPD test kit. Here are the results on 4/22:
Fc 5ppm
Tc 5ppm
Ph 7.4
Ta 150
Ch510
Cya 130
We added 1 gallon acid on 4/23 and 1gallon acid on 4/24 while aerating with a small fountain pump the whole time. Results on 4/25:
Fc 5
Tc 5
Ph 6.9
Ta 100
Ch 500
Cya 130
The fill water is well water and may have metal in it. I put some vitamin c on the stains but it didn’t dissolve. There was very little change. What should I do? Do I need to drain some water for the ch? How much would I need to drain to get it down? I read where a high cya on residential pool is not that bad just going to cause a little more chlorine use. I’ve ordered 5 lbs of ascorbic acid. Should I treat the stains before I drain the water or after? I really need advice on which problems are the most important and what order to deal with them. Any help would be greatly appreciated.
