sorry about that the pool is a AG 12k 15x30. Didn't test cya yet because i just put the plunks in yesterday and i thought it would take a while to show up. Also is it true that you can only test cya 2 times with the hth 5 in one drop test? i'm going to be putting the skimmer and pump in tonight and add bleach. also the hardness is probably lower than 10 the test didn't turn red it was purple and one drop made it blue.
