Hey all...
I posted a thread in the wrong spot last week, and an admin moved it here. Not sure if that's the best place, but that's where they put it. I had some questions that didn't get answered, but I forged ahead anyway. I've applied the first round of AA, and have a follow-up question... I'm posting this in the same forum as the "how to" thread, so hoping it gets in front of a few more eyes than that first one.
Before beginning, I had the pool at 7.2 pH and 0 FC, and I added a quart of Polyquat 60 one day ahead to be sure I didn't start getting any algae growth. I applied the first 2.2 lb (1 kg) bag to my 30 kgal by sprinkling it out around the edge of the pool, including a couple of sun ledges. That works out to 0.7 lb per 10kgal and slightly above the initial dosage recommended (0.5 lb per 10 kgal). I saw immediate lifting where the powder went into the water near horizontal surfaces (yay!), so I assume it mixes slowly and didn't diffuse much before hitting them. I waited 30 minutes and clearly lots of staining was left - especially on the walls (boo!) - so I applied the second 2.2 lb bag which I had purchased, bringing my total dosage up to 1.5 lb per 10kgal. Same thing happened again - the horizontal surfaces continued to lighten, but the walls weren't as quick. I tested the pH after that had circulated for a while, and it is around 6.8 - 7.0.
I am now circulating overnight hoping to see the rest of the staining gone tomorrow... it's going to be a bit like Christmas morning for me when I wake up. I'm asking ahead of time in the scenario where Santa leaves me a lump of coal in my stocking - if the stains aren't all gone, it's going to take me a while to obtain more AA. Should I go ahead and dose with sequestrant, or leave it as is until I get the AA?
I don't fully understand the chemistry, but I don't think the sequestrant would prevent another round of AA from doing its job down the road a few days. I'd like to start putting chlorine back in the water so we can swim, but that is only going to happen after I'm done with the AA. This is really about what the right holding pattern should be if I need more AA.
Thoughts?
