Which one is better for the fish? I'd imagine smaller water changes would cause less ph fluctuation thus shocking the fish less. But since I'm using the python method, I'm afraid I might be dosing the tank with too much prime as it accumulates over time. I thought about using less prime (enough just to dose the amount of water I'm changing), but am afraid that because it's diluted with 90% of the water in the aquarium, the chlorine would kill off my beneficial bacteria.
