So--- last summer my CYA was 100 bc we were new pool owners and used pucks all summer and found TFP in September...
. Now CYA is 25...?
I mean-- we did let a little water out of the pool last fall and got it down to about 60 before winter-- and we are in North Florida (sunny)--but isnt that a big loss in a year?
Am testing wrong?
I put my back to the sun, hold it at bellybutton level... should it be in the shade of my body or should some sunlight be hitting it? When sunlight hits it, I can see the black dot when it's all the way at the top-- I mean it's small but I can make it out. It JUST barely disappears at the very very top. (25?)
If it's in the shade of my shadow, it's more like 30 when I finally cant see it.
I threw a couple of pucks in the floater last week, but no difference in CYA. Have had to add about 5 inches of hose water in the last 2 weeks bc no rain and 88 degree days.
I want a CYA of about 40-- it seems to eat less chlorine at that number.
Am I doing something wrong with CYA?
Here are the rest of my readings from today:
FC= 9
CC= 0
Alk= 75
Cal= 200
pH= 7.6
CYA= 25
