As I have said,additives in any tank are dangerous to the inhabitants.That is not just a theory its common knowledge.If there is something going on in your tank that makes you feel you need the additives then you should simply fix the problem.Almost every member of this forum is capable of maintaining a natural system and do without the addition of additives.Maintaining a tank with additives is indicative of the state of aquarium technology 10 to 15 years ago.With appropriate amounts of live rock,live sand and functional refugium all the additives become completly useless.They actually equal a "natural aquarium system".You neglected to comment on the use of tap water.
