Below are my first set of readings. Water was 66 F, ambient temp also 66 F. Sample taken into house for testing.
FC 4.0
CC 0
TC 4.0
pH 6.8
TA 80
CH 260
CYA 50
Pool calculator said to add 68 oz by volume of soda ash to raise pH to 7.5.
I know soda ash will also increase TA so I only added half the amount (34 oz) and will retest to see where that takes TA. Then either use soda ash or borax to get pH to 7.5.
Does this sound right? Also, with no CC do I still need to raise chlorine to shock level of 20 (CYA of 50) or just up to target level of 6?
Thanks in advance for any help. You have all been very helpful so far!! I love this site!
