Calcium Hardness

Hmmm. Ben and I seem to be following each other around the forum simul-posting!

Thanks Watermom. I guess on that post I should have said the above results that I previously posted were from Leslie's. I am not sure what kind of kit I have at home, but I will retest this afternoon to see where I am at. Do you recommend not using the tabs? Is there something better you would recommend?

Thanks for all your help!

Elliott, you reported that your CYA is zero, but have been using 3 inch tabs i.e. tri-chlor. Tri-chlor adds stabilizer, so this doesn't seem possible. Possibly it is VERY high. You should determine you CYA with a good kit. If these results are from Leslies, it's a good indication why Doc and Watermom (and most of us "regular folks" on the forum) distrust pool store testing methods. How much chlorine you need to sanitize is directly related to CYA.

Good catch, Nef.

Ok. Thanks so much. I will get a good test kit and test for myself!
