Just buy those AquaChek test strips. eBay and Amazon have them a lot cheaper than Leslie's. The can comes with a color chart to hold the wet strip up against. Adjust chlorine, salt and acid accordingly. I do this once a month in cold weather and every few days when it's hot. Keep your chlorine up or you will end up with mustard algae. Keep your skimmer and filter baskets clean and check your pump pressure gauge. Mine is now at 20 psi, which means I need to tear it all down, clean the grids and then re-add diatomaceous earth (DE) at the skimmer. I have a guy come out about once a year when an issue with the pump, filter, seals, etc. is beyond my abilities. He gets me chlorine at wholesale too.
