I received my test kit Saturday and just completed my first tests: FC 6; CC 0; pH 7.4; TA 50; CH 320 and CYA 50. The testing appeared daunting at first, but soon everything was going well. And using the "Pool Math" calculator just makes every thing that much easier. I'm so glad I "drank the kool aid". Thanks to all who make this testing process so easy!!!!:
