I am sure you have seen the above chart. You should shoot for 15 ppm, but if it goes to 20 or even 25, it will most likely not damage or fade your liner because you have stabilizer in your pool.

You should have total chlorine. That is Free Chlorine + Combined Chlorine which equals Total chlorine. Don't worry, just post your chlorine number. My neighbor's pool was one cloudy, dirty mess. I tested their water with my kit and never had a positive combined chlorine reading. Took 1.5 weeks, but we got it clear. They just need to keep the vacuuming up.

Just make sure not to go over 20 ppm (parts per million) of chlorine in your pool. Try to keep it that high every day. Vacuum to waste every day. Don't forget to refill your pool as necessary to keep it around the middle of the skimmer entrance. You should see a difference in your pool in about a week. You must vacuum regularly (and not into the filter) and I would brush the walls every other day.

Keep up the good work. If you have any questions about backwashing, PM me and I will try to help. As stated earlier, any time you move the handle on your filter, Stop the pump first.
