It looks like my pool will have to be drained, refilled and re balanced. This time I want to do it myself and use the BBB method! Heres the situation:
1. FC over 5.. maybe 10
2. CC off the scale as well
3. PH 7.4 to 7.5. I tested 3 times
4. total alc 150
5. calcium 290 to 300
CYA over 200. I tested three times. Also diluted sample 50/50 with distilled water and multiplied x 2. Test results consistent
Pool has an unpleasant smell. It is normally covered, but is now open and in direct sun.
The water I want to refill with has a PH of 7.5. total alc of 40 FCL 0 calcium 40
The pool is plaster, 1 year old
The pool calculator says drain up to 80% and refill, so I might as well drain it completely
1. Will the cured plaster be at risk when I drain it? It will take about 30 hours to refill with my water source.
2. What should the sequence of chemicals be? I will have large quantities of BBB on hand as well as Acid, seqestrant and CYA
The pool is cured, but essentially new. I'd hate to ruin it!
Thanks for the help. Maybe I'm just over thinking the process!
