I noticed my salt water generator would occasionally flash green indicating a high salt level. Ideal salt for this Pentair model is 3400ppm, and it indicates flashing green means over 4500ppm. I think the very high pool temps, like 90 plus degrees, make it flash more readily. I bought a taylor test kit for salt and it indicates 4200ppm, I did the test 3 times and each time it would suddenly change from yellowish to brownish red in a single drop at 21, meaning 4200 ppm.
When I take the pool water in to be tested at Leslie's who has some sort of electronic device with a needle, it always comes up 3400-3500. I wonder if the flashing green LED on the Pentair SWG and the Taylor test don't read high when water temps are over 90.
DO I have to worry about a 4200 ppm salt reading? According to the Pentair manual it will still make chlorine but high salt levels can corrode equipment.
