Does everyone here use only tank water or dechlorinated water to rinse their filter sponges or floss in your canister filters? Normally I only use dechlorinated water for any filter maintenance but I'm wondering if it does me any good to bother using dechlorinated water for my filter sponges. I rinse those more frequently and when I clean the bio media I just swirl it in a bucket of dirty tank water. I'm just thinking I could get the sponges a lot cleaner if I run them under the faucet but I don't know how much damage it would do to my biofilter. I could always swish them in some tank water before I put them back in the filter just to make sure I don't get any chlorine in there. They just don't get that clean it seems like a waste.
