OK. As I said above, since your cya is a little high you either have to run higher than normal chlorine readings (see link above) or do a partial drain to lower it a bit. Your choice. Either way will work. Also, you need to lower your alk to between 80-125. You can read about how to do this in the thread at the following link.

BTW: Until you lower your alk to the desired target, disregard my advice in the earlier post to raise ph. After your alk is where you want it, if the ph doesn't rise up on its own, then you can add a little Borax to raise it to about 7.4.
