I have been using the TF 100 test kit since we installed our pool back in 09. I decided to order a new TF 100 test kit because I was getting some crazy numbers with the old one and I wanted the salt drop test and the stir kit. My pool stays open all year with the pump running, I take the Auto pilot salt cell off during the winter. Over this winter the pool turned green for the first time due to lack of care during the winter. Being in school now theres not a lot of time, anyway the my new kit came in today. I killed the alge over the weekend with bleach from walmart now the pool is clear. So here are my numbers
FC - 5.5
CC - 0.5
TC - 6.0
pH - 7.5
T/A - 160
CH - 50
CYA - 20
Salt- Drop test 3400 tested twice with same result
Salt strip test 2870 tested twice with same result
Temp - 73
Time - 7:00pm
I run the numbers in the pool calculator which told me to add 280oz of CYA which will be done gradually.
My question is with the T/A pool calcultor didnt give add or drop for this. So is there anything I need to do or just leave it alone?
The other is the Salt why is there such a difference in the Drop test and the strips?
If you guys think I need to make other changes let me know or are these numbers ok?
