Thanks also doesn't prime mess up the API master test kit reading? Many posts on here say that. And I'm just going to buy some buckets to solve the chlorine heavy metal and chloime problem. Can anyone tell me te exact ingredients, in order of prime so I can compare the two.
Prime detoxifies ammonia and nitrites, but it doesn't remove them from the water. They just get bound to other molecules and aren't harmful to your fish. It will NOT stall your cycle or remove your bacteria's food. It's your choice between prime and aqua safe, but I see no reason not to get prime. Prime's detoxification is an added bonus, it will help your fish, especially since you are cycling.
If aquasafe is causing you problems with water changes because you can't add it before the new water, then do your fish a favor and get prime. It should be about your fish's preferences, not yours. I'm sure they will thank you for not exposing them to chlorine.
