I know the place that I buy my bettas from uses different conditioner than I do. But when I bring my bettas home, after letting them sit in the water for a minutes, I just release them. They go from 1 conditioner to a totally different one right away and they're 100% fine. So why do we have to go through all this 75% old water 25% new water, then 50% old water 50% new water and so on when introducing them to a new conditioner? Can't we just introduce them right away? I want to do that because the conditioner I currently use measures by 10g and the tank is maybe 2g. I have no where to keep all the extra water. I bought a new conditioner that measures by 1 gallon that I wanna use. What should I do? Thank you.
