I am a brand new first time pool owner and I am blindly following the calculator.
I set up an Intex 18'x48" round above ground Ultra Frame pool.
Here are my levels using the HTC 6 test kit
TC / TB 5 / 10
CYA 0 - Threw in sock with stabilizer last night. When should I test for CYA?
When the calculator says to add acid to lower TA does that mean PH minus?
Thanks in advance.
