Always use tank water. I siphon into a 2 gallon bucket prior to a water change and rinse and squish the sponge in the bucket. It removes a ton of debris. And as Sheamurai said, I also believe there is a great deal of BB in the substrate. I once capped my substrate to deepen it (without thought) and ended up with a slight ammonia spike.

Since I use a python for water changes for most of my tanks, I always use tap water in a bucket with a little bit of Prime in it to clean the sponges and biomedia.

If you are concerned why not clean your sponges in dechlorinated tap water.When I go fishing I just throw sharp rocks in the water and wait for the dead fish to float to the top... Kingfisher
Everything happens for a reason. Sometimes that reason is you are stupid and make bad decisions.
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.
A moderator on a fish forum should be able to identify an oscar... Don't you think?
Dear naps, sorry I hated you so much when I was a child... Love me

But that will certainly remove at least some of the BB from the tank
A significant enough amount to cause any problem?...THAT is my question, all things considered

I use tap water and have for a long time now (even when I didn't have a whole home filter). When I did this, I would squeeze my sponges under the tub faucet until it would completely run clear. I don't rinse it in dechlorinated water, but I do wring it out as much as I can and re-add it to the filter. I've had no problems with this method in the year+ that I've practiced this method. All tanks would retain the majority of their nitrifying bacteria, which was enough to handle the current bioload. Params would consistently and still are consistently am: 0, nitrite: 0 & nitrate: variable.
My belief is that when you rinse the sponges enough times, the bacteria will consistently grow on the biological media and other surfaces in the tank. Then you needn't depend on sponges to retain any extension of your BB colonies and they're purely for mechanical filtration. Of course, now my sponges are gone and I'm relying purely on biological media. Though, I do still have prefilter sponges, which I have and will continue to treat the same way (rinse in the tap).

I think why waste any xtra Prime?.. and just clean them (sponges) in tank water that is pretty dang clear already, and safe to clean with?
AC sponges are coarse enough in my experience to come very clean if vigorously squeezed several times. Other filter media (pads) can come fairly clean, but will not hold up to repeated cleanings like firmer sponges.
Its been said that only enough BB exist to be fed by the stock of fish we have. Where those BB exist is important to know, but how sure are we were they are - in rings, filter sponge, prefilter sponge, gravel, all above.
If there are enough BB in the rings alone, one should be able to clean a sponge or Pfs without causing a spike I think, tho the BB may be evenly dispersed among all the bio-media we have in our filters,etc.
(I've was pondering these questions and doing some water tests and moving some media and cleaning of late)

Agree with Stingray: please change your "cleaning-expectations"!!! Better for your tank and fish I think. Cleaning in our hobby shouldn't be the same cleaning as a toilet aso. Bright and shining is a sin !!No Cory, No Glory !!

I disagree. Why should the aquarium have different standards of clean than the ecosystem you live in? There's "clean" and then there's clean. If you haven't rinsed out your sponges or floss in tap water, yet, then you really have no idea how dirty your sponges/floss get. You're not getting everything when you dip it in tank water, swish it around and ring it out. It's just not possible to get it that clean by this method. And when you use this method, you're just allowing the finer particles of dirt/poop to remain trapped in the sponge/floss. Your bio media, where the majority of your bb colonies live, if you've ever looked at it, remains relatively clean... ceramic, rocks, etc. doesn't/can't get that dirty in running water.
So, with that acknowledgement, the argument that "dirty equals more BB" falls flat on its face. I have disproved this theory time and time again, by getting my equipment in the filter as clean as possible. I shake my BB media around in tank water (which removes loos particulate matter) and I run warm water over my sponges to get them clean as possible, while ringing them out, yet I consistently have enough BB in my tank/filter to compensate for my bio-load, and let me tell you... my 40B has a pretty hefty bio-load. 4 BN plecos, 12 sterbai corys and 3 angelfish + 5 assassin snails, however many ramshorn/pond snails and RCS.
I follow the same practice in all of my tanks with the same results. Each type of filter media you have has a purpose. Why have so much BB media if you're going to rely on sponges to host colonies?
