The reason Jan suggested checking chlorine several times through the day and adding chlorine each time is that without CYA in the water, your chlorine will be depleted quickly.

Don't shock to 30 or 50ppm! The downside to taking the chlorine level too high is that you may bleach out your liner. The shock level she suggested is adequate for now. Once your CYA is raised, then your shock level will also be raised. See the Best Guess Chlorine Chart in Jan's signature above for more information about the connection between CYA levels and chlorine levels.

We'll be looking for your readings with your new kit!
