Cloudy and white dots

[PoolDoc]

If your weather is cloudy, so you don't lose much chlorine to the sunlight, keep it high.

Otherwise, if you can only measure to 5 ppm, let it drop just below 5, and then re-dose to take it to near 10 ppm, till you have a kit, and can manage it more accurately.

How do you use the TSP? I have 2 c400 cartridges that were at 8psi and now are at 20 psi even after I rinse them.
