I found this site late last year while building my outdoor kitchen, and have made most of my posts in that section. I started searching this site for pool info(since I have one!!!), and have just started to come around to the BBB method after using tabs and granules to stabilize my pool since it was built in late 03'. Purchased a DPD test kit, and am hoping some of the guru's on here can provide some guidance/advice as to where to start getting my pool balanced.
First, the info on the pool:
Inground, plaster, approx. 18500 gal. Starite 450 sq. ft. cartridge filter, 1 1/2 hp circulation pump motor
Current pool temp is 64*, and rec. full sun for 75% of the day.
I am just about ready to get the pool open for the year, and after going to "Pool School", and reading it about 6 times, I finally understand where I think the water values should be. I am currently having a slight bout of mustard algae on the wall on the shaded side.
FC/CC- The pool needs to be shocked, I beleive. Based on my current CYA level, where do I need to take it to?
PH- a little high. Should I adjust before shock?
TA- I know this value is affected by PH level. Should I adjust PH and re-take this value? If not, should I adjust TA level now?
CH- According to the recommended levels at PS, this is low. Adjust when??
CYA- I know the use of tabs. over the last 6 years has increased my CYA level, so a partial drain is in order to bring this value down. Any advice as to how much I should drain?? Several smaller ones or one big one?? Do it during the night hours to avoid direct heat on the plaster?? Does that even matter??
I look forward to any/all advice you good folks can give. I think one of my biggest questions is what order to start adjusting the needed values?? Thanks for any/all help in advance.
