hi alan
what spot are usually a syptom to unstable tank condition or water quality. it may be good to check the water condition and to ensure that all equipment are working....you mentioned that you used the salt, may i know your dosage? it should be a minimum of 1tbsp to 5 gallons of water.
If you need to switch to med, interpet white spot may be a good choice as it is bio and plant safe..next will be coppersafe. As for the waiting period, i would say about three weeks...I dont think there us anyway to shorten the time......
