I recently dosed my tank with a few meds and some salt. I used API super ich cure, API erithromycin, API Melafix, and salt. Literally a few hours later my stag horn algae problem had already started to turn red and is dying. I would love to know if it was the salt or the meds. I dosed them all regularly by the instructions accept for the salt for which I used 1 tablespoon to 2 gallons of water.
