The thing that I don't get on any fish keeping forum is that everyone says rinse in tank water. I'm guessing that's due to chlorines and chloramines that will kill off the BB. What if you have neither? Because my home is on a filtration system that keeps my hardness under 200ppm and removes them both.
My filter cleaning practices are relatively easy. I have let my FX go for almost year, I also started to notice my impeller making a little noise and I regret doing that. Could be shear age too because it's 10 years old. Depending on my stock practices are 1-3 months at most. So when it's time to clean my media, I take it out in my driveway, flush my hose first, and then spray down all my media. Only one time have I caused a spike and that's because I had an emergency to take care of. I quickly filled the filter up, set the lid on it and left for about 2 hours. Returned, cleaned and put it back on. I showed a spike that I had <5 ppm ammonia, <10 nitrite, and ~30 nitrate. Did some religious and huge WC's for the next 3 weeks until everything went back to normal. My tank typically doesn't even register on nitrates it's so low. I feed 1-2 times a day 2 pinches of flakes and 1-2 large pinches of cichlid peewee for my fish. Stock is in signature.
Edit: the signature that did not show up lol
