Chlorine level

[Rjfagan]

I had an algae problem but I finally got that taken care of, then I ended up with staining on walls so I used the product vanish.
That took care of it and now my water is very clear. My cya was low so I added stabilizer but still getting no chlorine level.
I shock and then show level for day then back to nothing.

Can you post a complete set of pool water chemistry test results from using your own test kit?
I suggest you read through Pool Care Basics - Trouble Free Pool and even look at a few of our videos TFP-TV - Trouble Free Pool
