Aqualogic T-15 cell installed, went from 2900 to 2600 in 2 days. I have changed nothing and added/lost no water? reading like around 24V and 4 amps. Tested water with my Aquacheck strips it says 2880? I hate these strips, wildly inaccurate. Cant read the serial number on the cell, but it was replaced I believe 3 years ago. I know the salt is a little low(3000) I'm guessing. But before I dump allot more salt then I need, like to see what you guys think? Cell going south?
