Yes wait till you know your CYA level to SLAM. you have to know your CYA level so you know what your shock level is.
Your FC level is determined by your CYA level pool-school/chlorine_cya_chart_shock
For a CYA level of 50 your FC levels should be 4-8 ppm and not below 4
For a CYA level of 80 your FC levels should be 6-10 ppm and not below 6
The CYA is a buffer for chlorine so it's not so harsh,and protects it from the sun, if that makes sense.
What is CLEAR 03 ?
