If you clean the sponge right under tap water, yes you will kill BB

Having a free flowing sponge is important and swishing them around doesn't effectively clean them nor does cleaning your sponges affect your BB colony in your Biomedia.

Lack of planning on your part does not constitute an emergency on my part.
Why pretend there are no stupid questions? Actually, There are many stupid questions: "Should I drink this bleach?" Is just one example.
Having said that, Just because it's a stupid question doesn't mean that it shouldn't be asked. It's better to know.
A warm beer is better than a cold beer. Because nothing is better than a cold beer, and a warm beer is better than nothing.

If you do rinse the sponge in tap water be sure to dip it in dechlorinated water before putting it back into the filter.When I go fishing I just place a sharp rock in the water and sit there waiting for all the dead fish to float to the top... Kingfisher
Brutal honesty will be shown on this screen.
I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.
Tolerance is a great thing to have, so is the ability to shut up.
I can explain it to you, but I can't understand it for you.

There are a lot of reasons, or excuses for every option on filter sponges or media. Unless you soak them in chemical solutions, such as chlorinated water, you aren't going to kill off all the bacteria in one. Disgust with how the sponge feels while I'm cleaning it, determines my clean or replace decision.
When it's time to change your AC size sponges, or any you cut down from AC refills, check Big Al's or Amazon.com for generic options. I pad out my online orders with extra foam inserts so I always have spares. I use them in, as is or cut to fit, many different filters, and as replacements for air driven sponge filters.

I wasn't asking about my sponges, I was asking about the biomedia, but that has been answered and then some. Thanks all for the advice and suggestions, you've been a big help.

Porous biological media does need to be replaced periodically. The micro pores that make it so efficient, fill up over time and can not be flushed out.
Each manufacturer has their own recommendations, and most people ignore those completely and argue about it online.

Or does clogging of the biomax pores simply result in a slower flow but not necessarily affecting the BB? Wouldn't some BB still survive on the outer surfaces of the ceramic beads?
How can one tell visually, just by looking at the beads, if the pores are clogged? Would the beads discolor, or is discoloring a harmless natural occurence over time? I know this happens with airstones, yet they still emit plenty of bubbles.
I'm asking so I can reasonably gauge when and if my own biomax would need replacing.
If the biomax has to be replaced, then it would be necessary to reseed the filter when new biomedia is introduced. Until that new media can grow its own colony, I would think another filter would have to be running with established media in it. Seachem's Stability should also help the reseeding process.

Nothing "happens". A dirty sponge is just not effective or doing the job it should be doing. You can only rinse the debris out of them just so many times until you find they just aren't cleaning up as they should.
I replace the sponges in my canister filters, as well, and for the same reason. I find it no more unusual than replacing the filter floss or any other filter media. Bio-max never gets changed.....or hasn't yet. But once again........make sure you only do one filter at a time so you aren't causing any cycle set-backs.

I have never met anyone who said (with any authority )that bio media needs to be changed... ever... that being said,if you are using a sponge for bio ..it needs to be rinsed regularly

How anyone who has ever rinsed filter material, can say that the pores in ceramic or sintered glass media won't clog, is a mystery to me.

But that's not necessarily the case with biomedia that has a light bioload on it. With a light bioload, the pores don't clog as easily and biomedia keeps its efficiency longer.
So it's really a question of how efficient the biomedia has become.
Does that make sense? I hope so because it makes perfect sense to me. But right now I'm the only one listening to me, unfortunately.....or fortunately for you as the case maybe.When in doubt, do a water change.
