I am off from work this week and thought this would be a good time to perform the AA treatment. Been suffering staining for the 5 yrs I've owned the pool. Not sure the cause. Starting to think possibly 9 yr old heat pump refrig tubes. Not sure what they are made of.
I have a 5lb bag of AA. I placed a handful in a stocking and rubbed it along the stairs (yellowing stain for weeks). The stain lifted immediately. Stairs look beautiful.
The FC level was at .5 and ph at 7.2
I have a 20K gal pool.
Placed full container of Poly 60 in pool to start.
I placed 1 cup of AA initially and started to see stains lift immediately throughout pool.
30 min later I added more AA and again 30 min later.
The vinyl liner looks amazing. There are very, very light blotchy stains remaining but hoping they lift overnight.
I added an initial dose of jack's purple stuff (2 qts) when all was finished.
I plan to put pool on filter and let it run for 24hr.
Should I be concerned about the low FC level?
How long with the Poly 60 hold off algae, etc?
Is another round of poly 60 needed before I start raising FC levels?
How often should I maintain adding sequestrant? How much should I be adding? 8-10oz?
Are their cheaper sequestrant agents available? Jack's is costly.
