Today is day 7 and I think I'm there.

I did lose quite a bit of chlorine during each day, but always kept it high overnight.

My cartridges are almost like new with all the bleach I've been subjecting them to and lack of biguanide.

I can see the bottom in the deep end and now see all the silt that I need to get up.

Now the next question for the chlorine section, how do you know what level of CYA is best?
