I believe there are different types of surfactants. The rule of thumb should be to never use an ammonia source with any ingredients other than ammo and water. I can't begin to tell you how many people here on this site have had a cycle not begin, and we discovered the cause was surfactants in their ammo. I'm sure some types wouldn't impede a cycle too badly, but I'd always suggest avoiding any ammonia that contains any additives.
