Remove CC

[gkarag]

I have been testing chlorine during evening and morning fo a few days and there is about .2 to .3 usage also noted CC is about .2.
How can I get rid of the CC.
Figures are
FC 4.2
CC 0.2
PH 7.4
TA 50
CH 550

CYA 500-550
Pool size 5000 ltrs(13200 gal)

You don't need to worry about any CC of 0.5 or lower. 0.2 is the lowest measurable in the FAS-DPD chlorine test if you are using a 25 ml sample size. The actual CC could be less then 0.2 -- the test is just saying it's between 0 and 0.2 and is certainly not a problem.

CYA 500-550

How did you get a reading on the cyanuric acid of 500 to 550? If it really is that high, then you need to get it down before you will be able to maintain good water quality on a consistent basis.

Sorry my mistake CYA is only about 40 to 50. I have an automatic SWG unit for PH and chlorine so I try and keep CYA at no more then 50.

CYA of 50 is low for a salt water pool. Your SWG won't regulate your pH, unless you have some new unit I've never heard of.
