It's interesting comparing the pool numbers to mine. According to them, the pH was the same, but hardness was lower than I tested, and alkalinity was lower than I tested...enough to make you buy their stuff to bring those parameters up...which I admit...I did before I tested it with the Taylor kit...

A question about adding the muriatic acid to bring down the pH...will it lower the TA as well??...that is main reason I joined this forum...if you read my second entry on this thread...that is what I am confused about....how do I lower my pH without affecting my TA??...at the time back in early July, I thought I had low TA as well, but now I see I am good there...

CYA - I performed the test as instructed in the manual and as you described above...but for some reason, even though the pool company test showed I was good on CYA...the Taylor test did not show enough to register...(I still saw the black hole at the bottom)...I guess I'll add another pound of CYA....I'm nervous about adding too much without allowing what i've added already to fully dissolve...

I only use trichlor pucks and then the combination of cal-hypo and 6% bleach...

I'm going to test the FC level tonight to see if I could back off the two bags of cal-hypo or two 1.42 gallons of 6% bleach every other day....does that seem like too much???
