Yeah, I'll have to go over the thread I saw again before I do anything. I always have at least 30g of heated saltwater on hand so I'll just make sure its full 50g. I have a large air pump I run in the fish room for my fresh tanks it will be no issue to run an airline or two to my reef. Iodine didnt work unfortunately. I have Iodine dip, oxolinic acid on hand and redslime remover (erythromycin). I tried a standard dip of iodine and a heavy dip, a standard 10ppm dip of oxolinic acid and a dip of redslime and treating the tank with it also. Affected corals were fragged and put in a 10g holding 7g of water with a small powerhead for about an hour maybe not long enough.
