After the 1000 year flood I had to get my water back in order. Added salt to get to (according to strips) 3240ppm. My Pro Logic thinks I only have 2600ppm. How ,if any, does this affect my SWCG??? Last year I only had to run it at about 10-15% and this year I am running it at 20% and barely keeping my chlorine at minimum. Same pump run time. Does the cell have to work harder when it things there is only that much salt???
