oh i see. yea i rinse the sponge that's in my Aquaclear as well. I've also had to do some cleaning for the container that holds the media & around the impellar. that part, imo, is quite time consuming & was wondering if a similar process is needed for the Emperor 400.
thank you for your input marisa!
* anyone who has an Emperor filter, please let me know your cleaning process with it. do you just rinse/replace the filter pads for it or is there a much more needed cleaning process for it?
