I have a 350b running on my 30 gallon and to be honest i always rinse the cartridges under tap water to clean them. I know it would be better to just rinse them in old tank water but i rely on my bio wheels.
sorry but the whole filter houses beneficial bacteria, not just your biowheels. You should not wash filter media in chlorinated water unless you wish to kill off the bacteria on it. What your doing is dramatically reducing the amount of bacteria in your filter. It may not be enough to cause a mini-cycle by itself, but if you ever pair it with something else things could be disastrous. Something else like increasing stock shortly afterwards. Filter media should be rinsed in dechlorinated water or old tank water. I prefer using tank water simply since its not a waste and its right there during a water change.
