Latest Numbers

[jborders5]

I've not done a good job of keeping up with full tests over the winter season (just chlorine and pH a few times a week. Here are my latest TF-100 test numbers. Should I be concerned with the T/A or CH? FYI, I'm doing the BBB method with liquid chlorine. Thanks!

3/10/13
FC - 4.5
CC - 0
TC - 4.5
pH - 7.5
T/A - 70
CH - 440
CYA - 30

Those are fairly good numbers. CH is a little high, though acceptable and CYA is a little low, though acceptable.

I would raise CYA up to around 50 since it is the start of the pool season. That way it will still be at least 30 by the end of the pool season.

You probably want to leave CH alone and just not add any calcium. Either it will go down to a better number next season or it will go up and by next season you will have to do something about it. But for now, you should be alright where you are.
