I'm telling myself I've graduated from "Just Getting Started"....to "Testing and Balancing Water"....
I've been using the TF-100 and managing the pool since a renovation in April 2014 (that was the fill date). I just tested the water with the following results:
FC 5.5
CC 0
TC 5.5
PH 7.8
CYA 25
CH 325
ALK 60
Borates - 50
Pool crystal clear
I don't understand why the CYA has dropped When I filled the pool in April, I got it up to 40 and have been chlorinating it to maintain 6 (yes, that is a tad higher than recommended (Chlorine/CYA chart) but I am in Texas and the pool is in full sun all day and I'd rather be safe than sorry (then letting it drop below 3 before I get home from work).
Anyway this morning, I've tested the CYA over and over and it's 25. We have had about 8 inches of rain since April and I've had to drain off about 6 inches since that time and have had to add about 4 inches due to dry spells and evaporation.
I'm nervous that I am over-analyzing that black dot in the CYA test tube, or perhaps have under analyzed it these past few months. I'm scared to add stabilizer because I don't want to jack it up to much so I'm thinking I will put pucks in the chlorinator and just test the CYA daily until it's up to 40.
Can it drop like that?
