Yesterday I opened the pool (took off the cover) of a IG 22000 gallon 37' Gunite pool in Round Rock, Texas. I waited until my Live Oak trees stopped their daily dumping as they do every spring.
The water was crystal clear with no algae. This was nice to see, and a good reward for keeping up the bleach and mauratic acid treatments over the winter, about 3 large jugs Bleach per month, and 1/2 gallon acid per month to keep the PH down. I also ran my pump on low speed 4 hours per day.
I dusted off my PS233 test kit (stored in dark place in my house), and here are the numbers:
FC 1.5
CC .5
TC 1.5
PH 7.8
Alk 160
Cal 220
Cya 0
Temp 74
After this test I added another large jug of bleach, and 1/2 gallon of acid....
Last Fall before shutting to pool down I had:
FC 4.5
CC 1
TC 5
PH 7.5
Alk 150
Cal 300
Cya 50
Temp 76
My question is, "Where did my CYA go, or is my test kit result inaccurate from being old?" I think I will see Marty at the pool store with a sample before I decide to add CYA. What needs to be replaced in the PS233 kit year to year?
Thanks,
Jim
