I have added my aa for my treatment to get rid of my reoccurring metal staining, but I have a few quick questions. The stains are all gone and the pool looks fabulous! My test results are:
I lowered the Ph and TA using muriatic acid, my TA was 150 ish and i wanted to bring it down and it brought it to the 110 it is now. I have added about 12 oz of powdered Borax to try to raise my Ph. It was all i had on hand. I also have my return pointed up trying to aerate as well. My goal this go round with the treatment was to drain most of my pool after sequestering and refilling the pool.
Can I go ahead and add my sequestrant even though my Ph is still low? I added the ascorbic acid about 3 hours ago and the Borax about 30 min ago.
How can I raise the Ph without raising the TA?
How long after adding the sequestrant should I backwash and drain?
My fill water tested at 170 TA, so once I refill i am still going to have to lower it. What is the best way to do this? I suspect the reason for my stains returning is that my Ph always rises fast, and i think it might be the TA. Any help would be appreciated!
I believe the metal staining is due to the tabs the previous owners were using, I was told they contained copper. I also had a few rusty screws around my skimmer basket that i have replace with stainless. HOPEFULLY once I do this treatment and drain i won't have any more problems.
