Hello all. This is the third day using my TF-100 test kit. Now that I'm sure I'm using it correctly, here are my results:
FC - 5
CC - 0
TC - 5
pH - 7.5
T/A - 150
CH - 340
CYA - 20
Today is 2 weeks since I filled my new Intex 20x12 eliptical pool (4400 gallons). I was "pool stored" at first but after attending pool school and reading many posts in the forum, I'm now confident that I know what I'm doing. I shocked the first night with half of a bag of Power Powder Plus then 3 nights later with the other half. I'm floating three 3" chlorine tabs day and night with the floater opened up all the way. FC seems to be staying between 5 and 6. I'm concerned that the T/A level is high but based on what I read in Pool School, I shouldn't try to lower it:
"There are two reasons to lower your total alkalinity (TA). High TA combined with aeration can cause rapid PH increases. High TA can also contribute to a high calcium saturation index (CSI). If your CSI is too high, you may get calcium scaling.
But you shouldn't lower TA just to reach a target number. Make sure you actually have one of the above issues before lowering your TA."
CYA is low. Should I continue to use floater with tabs or should I switch to bleach? I assume that over time the stabalizer level will rise even using the tabs.
Thank you,
Joe
