From pool school I have gotten the following recommended values -
FCC - 4-6, shock 24
pH - 7.5-7.8
TA - 60 - 80 (SWG man says 100-120)
CH - 250-350
CYA - 70-80
Borates 50
Salt 3000 - 3500
CSI should be between -/+ 0.6
Other than the big difference in TA suggestions between here and the manual for my SWG, no problem. On the difference, how critical is it, and what should I be using?
When I opened the pool, I run the filter for a few days without doing much to the chemistry - I know that I will be backwashing at least once to get rid of all the winter 'leaf tea' gruck, so don't want to waste the stuff, etc... Turned out to be longer than I was expecting because of rain, but....
Opening test (filter had been running a few days) 6/4
FCC - 0 (OTO test only) (no surprise...)
pH - 8.2
TA - 150
CH - 350
CYA - 20
Borates 20
Salt 2000
Pool calc suggested
85 oz 12% bleach
130 oz muriatic
107 oz CYA
134 lb salt
565 oz borates
added
~ 1 gal bleach
3 gallons muriatic
remaining amount owned of CYA - I'm guessing about 3 lbs.
80 lbs salt
~ 2 boxes borax
6/7
FCC - 5+ oto, 4.5 dpd, cc-0
pH - 6.8
TA - 60
CH - -
CYA - -
Borates - 30
Salt - 2400
suggested
144 oz of borax for pH
377 oz borax + 180 oz muriatic for low borates
80 lbs salt (added 40 lbs)
(need to go buy the borates...)
the big concern is the CSI = -1.15 which is BAD per the pool calc.... How critical is it that I get this dealt with right away? I know that adding borax will bring it back up, and the CYA that I added is still dissolving, so how much of a panic is it?
BTW, this is my first year using the Taylor salt test kit - seems like a very nice test, as it has a really clear end point - goes from yellow to red in one drop... Don't know why more places don't use it.
