It's not that. It's not worth me risking if I missed some eggs on a coral and then it gets out of hand and spreads more through my whole system. I'm working 12-15 hour days so I'm out of the house13-16 hours 5-6 days a week I just don't have time to come home and inspect and radip 45+ frags on top of my display. I would rather not take a chance. I really would hate to spread them to anyone else's tank. No dip has has been found to kill the eggs and everything without question. My frag tank is tied into my whole system of 900 gallons.
