I'm going to be moving from home back college soon. I have a ten gallon cycled tank with 4 cories and a betta. Currently, I am using well water to fill my tank but I will be switching to tap water when I get to school. Does a change from well water to tap water affect the cycle of the tank? I'm a bit concerned that a change in the cycle will hurt my cories since I know they are sensitive to ammonia and nitrites.
Also, does anyone have a suggestion for how to preserve the beneficial bacteria from the filter and the gravel? Would keeping it in a bucket with a bit of tank water keep the bacteria from dying? It's a five hour drive to school and I would hate to lose everything I've established.
I have my system for transportation and acclimation all planned out so I'm really only concerned with the cycle.
