I had to partially drain my water (high CH and salt levels) and I wanted to make up for the lost CYA. Can I add the CYA using a floater? I know the suggested method is to add it via the skimmer but then I thought maybe this way I do not need to run the pump for 12 hours. Please let me know. Thanks again for all the help. Also it would be great if you could include the reason the answer is yes or no.
