its a fact that sponges in a filter don't hold as much beneficial bacteria as noodles or balls or what ever biological media your using. i'm in the process of cleaning my sponges in my fx5 and i know your suppose to clean them tank water but it just works sooo much easier when you can blast them with water from the tap. so basically i think will be ok cleaning my sponges with tap water so long as i leave my biological media in the filter. my fx5 is currently brimmed in each compartment with biological media so i think i will be ok, but i just wanted to hear your views.
