A few posts back it was suggested to measure salt levels every week.

I just put in a new Autopilot digital last week and it will display the salt level. Mine shows 2800 which agrees exactly with the test kit. It also says to add 36 lbs of salt, which it calculates from the setup page where you put in your pool volume.

I keeps getting better and easier.

If you really want to blow the bank, you can add on the ORP kit and an automatic muriatic acid pump .... totally auto.
