Opened for first time with old loop loc mesh cover green swamp

The ideal chlorine levels depends on how high your CYA level is. Take a look at the Best Guess Chlorine Chart in my signature below for more about that.

I don't know what the chart is supposed to do. If I don't dump something else in there my readings won't go up from zero or zero - low.

My advice to you is this.....read all the stickys in this forum and take the time to really understand the chemistry of a pool and how each number affects the other. Once you understand that, just follow the BBB method. Get a good test kit (Taylor 2006c) and whack away with the chlorine. It's simple but difficult at the same time until you understand the process.

I too have a loop-loc mesh cover, this is my 2nd season with it. My pool has been a swamp both times I opened it. Previously I had a regular solid winter cover, held down by water bags. I got tired of pumping off the cover, and cleaning off the leaves. That's why I went with the all mesh cover. Do not replace your old cover with an all mesh cover. There are 2 other loop-locs you can buy, one has a couple of mesh panels that let water through, the other is a solid cover with a pump. Either of these will prevent your pool from turning into a swamp over the winter.
