mustard, Welcome to this forum. I'm sure that you will find very useful information here. 1) The cycle length of white spot disease is three days. It takes three days for white spot parasite to complete its cycle from get embed into the skin of fish, become mature and finally release from the fish. Medicine applied to tank water can only kill the free parasites in water but those embedded in the fish skin are protected. Therefore after medicine has been applied for about 3 days, these protected parasites will mature and developed into white spot and be released to tank water. However, when they are released into tank water, the availalbe medicine can kill them by now. Theoretically, after the first cycle (3 days afterwards), all parasite should have been killed. But I think 3 cycle lengths (9 days) should be safer. 2) You need a quarantine tank to prevent infected fish from bringing parasitse into an established tank. Or you may try other medicine that is "reef safe".
