Bonni,

Why do you have to get the chlorine up to 5 - 10?

Mbar- Is there a problem keeping it between 1-2?

So far, my water has been almost perfect. I am not planning on raising my Chlorine above 1-2 unless I see a problem.

All comments welcome.

**last year I had a problem with the cloudy water (same entex 18x48) Nothing fixed it. But my remedy this year if it happens again is to treat it like staining, add Ascorbic acid, which will bring down the chlorine and then slowly raise the chlorine again until it gets between 1-2.
