What does it hurt if you rinse a pre-filter sponge for a cannister filter (Eheim) in normal tap water vs. syphoned out aquarium water? Isn't the point to get the garbage off the pre-filter sponge and ring it out until it looks good as new for the upcoming week??

Thanks.
 
By the time your system has been up and running for a while, your biofilter everywhere all through it is pretty robust. I've just finished rinsing out a bunch of filters right under the tap myself.

But at the beginning you have to encourage all the biofilter microbes you can scrape together...
 
I'm with wetmanNY. In the beginning you might want to just rinse your prefilter through dechlorinated water. But once your filter has been running for awhile and you got yourself a stable bacterial population in your filter, go ahead and blast that prefilter with tap water. Its what I do.
