Hi all -
I finally now not only have a crystal clear pool but it's so blue it stings my eyes! It's beautiful and the ascorbic acid process worked like a charm!!! (Not that I expected differently from this place, but felt it was worth declaring.)
Now that the pool is sparkly blue (seriously, I joked earlier that it looked like we dumped blue paint into it by accident), I want to make sure that we don't mess anything up in the next steps.
To recap what has been done this week:
-Free chlorine has been continually dropping from a 7 on Monday to a 3 yesterday afternoon.
-Since FC was at a 3 yesterday afternoon and I just spent weeks SLAMing, we added the Poly60 algaecide at that time. So that container just went in yesterday afternoon.
-As of earlier this morning, the FC was down to a 0 and we moved forward with the ascorbic acid treatment to the pool. That was 4 lbs total.
-Within minutes, the improvement was noticable. Within an hour it looked perfect!
So the ascorbic acid treatment is about 2 hours in the pool at this point, but literally has erased any signs of a stain.
About a week ago, I added a full bottle of Jacks Metal Stuff for Vinyl Liner pools (which mine is).
My next steps questions are as this:
1. I have the Taylor iron test kit. When should I test for the iron in the water? Should I wait a specific period of time after doing the removal? Will the ascorbic acid throw off the numbers?
2. Adding FC - the big question - when can I start? I believe I found an old thread which says to increase it by 1ppm per day. Since I did the treatment this morning, could I start adding bleach tonight? Or is that too early and I should wait until the ascorbic acid has been in there for 24 hours? And most importantly, is that 1PPM like increasing your FC from a 0 to a 1 on the pool calc? Or is there another calculation I should be using to determine this?
3. Is there a chart I can use to reference dependent on my test kit results? IE should I be adding more than the recommended 8oz of sequestrant a week, etc...
Thanks so much!
