Great I think I got it, so here is what I do.
1. I buy stabilizer something like that http://www.walmart.ca/en/ip/hth-stabilizer/6000016956074
2. Add 900g (according to poolcalc) into the sock and hang it infront of the return.
3. I keep it there for a week or so, and after that do new CYA testing.
4. If test shows CYA 30 at the end of the week I do a SLAM to 12 with chlorine or bleach
Questions:
1. Do I have to run pump all week long non-stop ? or I can stop for a night.
2. Should I add anything else during this week, chlorine maybe ?
Thanks a lot.
