Hi all - just went to Leslie's and got the following results:

FC: 5
TC: Not tested (didn't notice until they dumped all my water out)
pH: 7.4
TA: 100
CH: 380 (using the 10ppm/drop method)
CYA: 60
Salt: 3300

I also ran a test with the same batch of water I took to Leslie's and got the following results:

FC: 3
CC: 2
TC: 5
pH: 7.2
TA: 70
CH: 375 (using the 25ppm/drop method)
CYA: 60
Salt: Didn't test

Notice the drop in pH after I put in 40 oz of muriatic at 1.5 hours ago.

Maybe I need to tighten up my testing? Specially the CH testing?
