I was going to just test the CYA using last night’s water sample. Then I’ll test everything else with a new (cold) sample right after. I’m adding borates to my pool today so I’ll definitely be testing the pH/TA with a new sample here shortly. I despise the CYA test and the cold water temps just make it more annoying lol. The bottle has been sitting since yesterday evening, so it should be plenty warm. No rain or anything since then.The CYA will be the same but the PH and FC may be different.
