Thank you - I will get the tester - it's one of the ones sold here right?

I will get the cya numbers. I know we had to raise it because it was very low when we started. I forgot to say, also, so that I use just straight bleach so my cya won't get too high - I raised it separately.

I will double check that I didn't misunderstand the cholorine numbers. Hubby checked 'em for me while I was in the middle of something else and I may have switched them.
