Of course it will be ok. You're losing 2 to 3 ppm a day and you have 6FC leeway to the 50 CYA min of 4.So i will not add any chorine tonight either. And hopefully tomorrow everything will still b ok.
You might not have 2 full days to spare if one day has particularly high UV, but tomorrow is all but guaranteed.
You're overthinking it with vinyl. Any 7 is equally ok. You used to beat it down with all that CYA (acid) so it *used* to be low 7s. It might stabilize higher now, but there is no 'more ok' than ok. If it's a 7, walk away.Do u think it will level off here or maybe even go down to 7.2???
Ok GREAT. Now test it monthly. It's no longer a concern.But the TA is staying at 100
Always walk away as soon as you get the endpoint of the test. If you take a few minutes cleaning up, anything else that happens doesn't matter.left the mixture in the tube while i cleaned up (about 5 minutes) and that solution became LESS red
