I would like to thank all of you again for the great help.

I received the Taylor k-2006c yersterday and here are all the test results.

FC 26 ppm
CC .5 ppm
pH 7.6
TA 140
CH 200
CYA 90

It has been raining for the last two days and Issac has added about 4" of water to the pool which I think helped bring down the CYA. I have quit using the inline chlorinator with the 3" tabs. I plan on using it again if we are to go out of town or if I need to bring up the CYA. One thing I should mention is that the water is very clear even after all of the rain. I do have a few more question for you if you get a chance.

(1) Do you know of a good pool volume cal? I have used several on the internet and all are giving me differant answers. I have a 27' round AG pool and the actual water depth is 49"

(2) What are the ideal levels for all test on my pool? Mainly the TA, pH, and the Ch. I think the best guess chart takes care of the rest!

Thanks again for all of the help! You have made be a believer!!!
