just a couple questions.... my TA is testing at 300 !!! i turned the "eyeball" return around pointing up, so i got the bubbles going, as i've read to do here, for about 5 hours before i shut 'er down for the evening. tested the next morning and TA was still 300. PH & clorine all test fine. just curious, as for the past 3 years i never tested for TA and never had any problems with the pool. (i just stumbled upon your site this year, so i never knew i SHOULD test for it) what would cause a level that high and what kind of problems will i have with a really high TA if i can't get it down ? is TA levels really that important ? and before you ask, no, i don't know what my CYA level is, cuz the test kit i have doesn't have a test for it.
thanx for the info oh gurus of the pool.
