Boyd's info is correct...it'll take a while for the CYA to show up. You also did the right thing by getting out of the skimmer into the filter...that'll speed up the process. Don't backwash 'til your CYA test reads about 30 -40.

Meanwhile, you are also smart to keep putting in Cl of 10% every evening.....it is being consumed by bad stuff...probably algae you can't yet see. Test each evening for Cl before you put it in and then put in enough to bring your total up to 10-15ppm.

The "bad stuff" eats the Cl at night and, 'til your CYA takes effect, the Sun eats your Cl during the day. It may not seem like it but you're doing all the right things and you'll stabilize soon.

Thanks for those numbers. You can work on the Calcium and Alk in another post.....you do not have a harmful situation with either....just some fine tuning to do.
