Dechlorinated tap water for cleaning

Hey all. We all know that when cleaning your filter media, especially those that house the beneficial bacterias, we want to use tank water taken during a water change as to not kill the bacteria. I am thinking that the filtering media in the canister filters houses these bacteria as does ceramic discs, bio-balls, etc...
What if you are not doing a wc but want to clean the filter out? Can you use treated tap water in a bucket set to about the same temperature as the tank? I am think yes.

What sayeth you...

Yes, I do that occasionally. I would alternate the rinsings rather than clean everything at once. Rinse the filter floss one time, the next time rinse the ceramic beads, etc.

I agree,but would point out that usually this is not necessary. Knowing you have a planted tank, Erik, I would not waste my effort with tank water or declorinated tap water. In 20 years I have always cleaned my filters under hot tap water, the media, the baskets, the filter housing, the tubes...and never had an issue. There is far more bacteria colonizing the plant leaves, wood, rock, substrate and tank walls that exist in the normal filter. Plus in a planted tank you have little need for nitrification bacteria anyway.

In non-planted tanks this is probably good caution, unless the tank is established and balanced (fish load with water volume, bacteria).

Thank you guys. I spaced out the fact that there are plants in the tank. I was focusing more on the possibility of unbalancing the bacteria colony. Thank you for pointing that out Byron. I'm focusing on too much this morning. Although I did want to be cautious before doing anything. It's disheartening to awaken in the morning and see a cloudy tank or dead fish.

Thanks again.

I'd not even worry about needing to clean your canister just yet, its brand new set up with about handful Tetra in there. Reason I'm saying this is cause people often fall for the habit on new stuff that they need to clean this weekly/ monthly whatever and actually do more harm then good on their filters that way. I clean my canister once maybe 2x year.
