Bio media

[akskirmish]

I was always under the impression that it needed to have water flow over it and trickle down to chamber where it is than pumped back to tank.

What if the bio media is submersed though? is this ok as well?

Yeah that's fine - it's how canister filters work - they are filled with water (flowing of course). The water has to be moving - if it is too stagnant and gets no oxygen the bacteria will die. But it can be underwater, sure.

Is one way better than the other?

I understand how canisters work..I thought I did with a sump as well...But would like to make sure is all...

I just seen one the other day that had me asking myself a few questions....
I appreciate info

It's really a matter of efficiency
The nitrifying BB need oxygen to process waste
there is oxygen disolved in (moving) water
however they are moar efficient in a wet/dry setup

Out of curiosity
how does one keep water in it's liquid form in Anchorage

I have a sump. I fill it up with a lot of water, and as the water evaporates out, it becomes a wet/dry. Maybe I'm just lazy

As long as oxygenated water is flowing over the media, it's working.

Could it be more beneficial to plumb in airline tubeing to create more oxy berfore it enters sump. or would this do nothing to help?

lol.....Right now outside...one doesn't....it is cold and wind blowing.....Inside.....There are tanks at my shop not even running heaters in them......we know how to insulate up here....

I have an air stone on in the sump before it gets to the media. Not sure if it really helps or not, lol.

Others certainly know more about how/why it is more efficient, I just know that as long as it gets oxygen it is ok under water - canister was just an easy way to explain as I figured you knew how they worked I'm interested to know more about the efficiency too though.

well I believe that the way it is plumbed and setup....when the water beging to enter sump it hits a drip plate that is filled with a bunch of holes-as it falls through that it then starts to hit the top of media which is not submersed and continues this way for about 4 inches down into sump where it then begins to be submersed full time....The in take for the sump is 2 1 inch pipes....
So I guess it does see enough oxy.......Maybe I am wrong...

Hopefully someone can chime in and give positive answer
