Yes I agree to a point that bacteria lives everywere in a tank. I didn't quit word my first post right. But I'm talking about the majority of the bacteria and its a really big majority. The BB does not do good at all in the water because it constantly moving so its in a desprate state to try and find something that it can attach it self to. Inside the tank itself theres very few places that it can attach itself to because the water always moving. So there for if it trys to attach itself to the glass it will eventually get swept away. That why with filter media we use things like sponges and ceramic rings that have pours that the bacteria can go in and won't have to worry about getting swept away. The BB also likes a dark area and a filter is always dark inside. It also needs a lot of Oxygen and the filter is the perfect place for this. I've read quit a few articles on this subject. If you don't believe me do a search and read up on it. Also take out your sand and ornament an test your water the next day. Then put those all back in and take your filter media out and put brand new in then test the next day. I'm not here to argue with you about this I'm just stating the facts.

Dude, idk where you got your microbiology info from but your mistaken. BB will live on any surface, they live on your skin right now as you read this. On your key board, mouse etc. Light (except concentrated UV's) and water circulation have squat to do with growing your bb. Nutrients, O2 and surface area have everything to do with it.

As I said before I know there is BB ever were in your tank but the big "majority" of it is in your filter. That is why if you have a filter with two pads you don't change them both at the same time you do one then wait and do another.

Do you know for sure that the "big majority" is in your filters?

I believe I have just as much BB (both aerobic and anaerobic) in my sand substrate as I have in my two HOB filters on my 125G tank. However, I can only speculate as I have done no scientific study that measures the BB count in each location.
 
In my years of HOBs, I always prefered the AC, you can easily use your own media, and I think it's cheaper on your wallet too. My roommate had the emperor and it was costly, noisy, and the spinning wheel stopped working in about a month. He switched to the AC about a year after.
 
I have a emperor 400 and two ac 110s....AC hands down

....the selling points for me are: simplicity, ability to switch media easily, and noise

the emperor is just louder and doesn't seem to push as much water IMHO

luckily theres an easy test for that.
pull all the filters off your tank, and see what happens. ;)
 
I effectively pull the AC110 when I change the bio-sponge. I replace the sponge with a dry one that I had rinsed out with tap water weeks earlier (filling a 5G bucket with tank water to rinse the sponge is a little more work and mess than I want to deal with). I have not detected any ammonia spikes after a sponge replacement on the two tanks that have the AC110's.

Exactly if you do have even bacteria levels in your tank and filter then you should be able to do this with no problem. Next day test your water piece of advise though bring a bucket with you. After about a month or so when your tank is done cycling again wait a little longer for the filter to get really mature. Drain you tank take out all the substrate and decor wipe the glass down with a towel and fill it back up. Test you water the next day now you may experience a mini cycle because as I said before there are "some" BB in your tank how big of a mini cycle will largely rely on how mature your filters are. If they just got done cycling then yeah your probably experience a small spike but not a full fledge cycle like if you were to take your filters off. How do I know this you say I've done it. What I've learned about BB I learned mainly from another forum what people have post very experienced people mind you so there for I can't bring any hard facts to so you because I can't find the posts. This is all I was able to find last night looking through articles.

"bacteria will cultivate in far greater populations, in any area where the highest amount of oxygen exists, which is usually in a filter system that is designed to promote their growth by supplying a continuous source of oxygenated water to the bacteria. This is where the term "biological filtration" comes from."

If you would like more evidence or are just curious try the things I mentioned above.
