Background: bought a home ~18 mos ago that has a pool. With no prior pool experience, I have slowly but surely been learning and resolving issues mostly from info garnered from TFP.com - many thanks!
Last summer, everything went well. Bought a TF Test kit, and we enjoyed a very fun backyard experience. The pool has a Poola-hoops basketball goal (previous owners left behind), and the rim was rusting enough for the paint to be peeling, but I thought nothing of it as the pool chemistry tested right. Over the winter, i slacked on testing and the pH drifted up to 8.0. And I began to get yellowing on the liner. Confirmed it as iron with the Vit C test. So I am preparing to do an AA treatment per the mbar recommendations. Still have some questions on FC management though.
Current test:
pH - 7.6
CYA - 75-80
CH - 100
TA - 80
FC - had been running @ 5.0, turned off SWG and it drifted down to 2.0 at which point I added 20 oz of polyquat 60.
CC - 0.0
Plan: add MA to drop pH to 7.0-7.2. Add AA and Purple stuff as directed by mbar. I found that afterwards, I should shoot for bringing up FC about 1 ppm/day until it holds at target for my CYA (5.0). When do I bring pH back up? Noted that I shouldn't SLAM for 2 weeks - but if my readings have been in range, do I need to SLAM afterwards or just rebalance?
Input and advice is appreciated.
(Oh, and yes, I already replaced the hoop with a stainless hoop from the Dunn-rite folks. Figure that was my source)
