Chlorine Problem

[ts8181]

Hello All! New to the forum and this is my first post. I have a pool that will not hold chlorine! Everything else I test is ok, but the chlorine. Any suggestions?

Welcome to the forum! If you can give us a little more information, someone here can try and help. What type of pool is this and what is the volume? What type of filter and what size of pump? We also need a complete set of current water testing results taken with a drops-based kit. Tell us exactly what all you have added to the pool, meaning ingredients -- not just "shock." Lastly, tell us what your CYA reading was when you closed the pool in the fall. Thanks!
