Day #7
I was only able to treat the pool twice today.
Used ~3 jugs (121oz @ 8.25%)
Up to ~31 jugs overall.
8:00am: FC was down to 13; increased to 15
8:00pm: FC was down to 0.5; increased to 15.
I did some brushing tonight.
I ran the pump with the filter on from 8:00am this morning. The pressure hasn't changed all day, so I am going to continue to filter overnight and backwash tomorrow.
It seems I should be on track to only lose 1ppm of FC overnight within the next few days. Once I do that I will clean out my filter and change the filter sand. I will then add ~54oz of CYA to get to 30ppm. My plan is to place that amount in a sock either in the skimmer or in front of the return valve. I've read it can take a week before CYA will show up on tests and I should continue to maintain FC at 15. Is sending the FC to 15 in the morning and then in again in the evening sufficient at this point of the process? Or should I try to do it 3 times a day as I did during the first part of the conversion?
Is there a "best" time to test CC? Once my CC's are 0.5 or less for 2 days in a row, I can stop maintaining FC at 15 as the conversion is considered complete, correct? I can then get the chlorine to the recommended levels. Is there a preferred order to bring the pool to recommended levels? FC, pH, then TA? And then after a week, I can test to see if my CYA is in an acceptable range.
Is there anything I should be watching out for, or anything that I may be missing in these next few steps of this conversion?
