#s for New to me Pool!!

[hedge089]

Hey guys. Been following here a little bit in anticipating getting a pool. Finally, moved in and got the pool tested. Here are my numbers:

FC - 0.5
CC - 0
TC - 0.5
CH - 675
TA - 110
CYA - 100
pH - 7.3

Overall the water looks decent. The previous owner was using trichlor tablets which I believe is part of my FC and CYA problems. Concerned about the CH with the plaster pool. Let me know what you guys think. Headed out to get some liquid Cl soon! Thanks,

Welcome to TFP.

That CYA 100 based on a diluted CYA test?

For CYA > 90ppm, repeat the test adjusting the procedure as follows:

1. Fill the mixing bottle to the lower mark with pool water.
2. Continue filling the mixing bottle to the upper mark with tap water.
3. Shake briefly to mix.
4. Pour off half of the contents of the mixing bottle, so it is again filled to the lower mark.
5. Continue the test normally from adding R-0013, but multiply the final result by two.

Draining 60% or more of your water will lower your CYA and CH.
