I am using a Walmart HTH brand test kit until my TF-1000 arrives. I took a sample to the pool store last week for a more accurate reading, but the difference seems to be to much. I wanted to add borates, but now I don't know if my TA is in line.
Pool Store said last week:
Walmart test says today:
CYA <30 (the drop disappeared just a few drops above the 30 line, the top of the bottle)
Do I need to lower the TA more before borates?
Is the CH too high? I don't want to replace the water after the borates. (I have a vinyl liner)
How much chlorine do I use? Thats a big spread for the CYA.
