CYA that is off the charts is something that most pool owners have no clue about. They just keep putting in those pucks, more pucks, more pucks, and some dichlor shock for good measure. All the while keeping their chlorine between 1-3 because according to their cheap little tester, that is "ideal." A recipe for a big algae bloom that they then spend weeks and lots of money trying to clean up. Knowledge is power and you have made a smart decision by reading on this forum.

Hope you have a great swim season and that we'll see you around the forum frequently. Glad you found us!

Edit: Keep an eye on your pH. 7.2 is ok, but if it drops any lower, you'll want to bump it up a bit. Come back in a day or so and give us a full set of readings.
