Prime reduce the oxygen level in the tank. It is used as a detoxifier for ammonia and crap not as a chemical filtration. If you have somewhat of a decent filtration system you wouldn’t need to dump it everyday. That’s about the dumbest thing I’ve ever heard. Not to insult you or your 15 years of experience. I’m sure 100% EVERYBODY will agree with me what you are doing is completely unnecessary and potentially dangerous to your fish. That being said let me ask you do you panic when you go a day without putting prime in your tank?My 15+ years experience must be an anomaly please share with me the danger you see in priming a new tank?
