I've just about used up my remaining Nutrafin Aqua Plus and I have a bottle of Tetra Prime to start using. I usually leave tap water in a bucket to dechlorinate for 24 hours after adding Nutrafin Aqua Plus, although in the past I have read on these forums that dechlorinator works in virtually no time at all; I like to err on the side of caution. That said, after adding Tetra Prime to a bucket of tap water, how long is it advisable to leave it for? Personally, I'd prefer to stick with 24 hours because that's what I'm comfortable with (I really don't want to cause any problems for my fish or stress myself out worrying). The bucket gets covered with a wooden board to prevent dust, etc, from falling into it during the 24 hours (no heater or aeration in the bucket either).
