For a Japanese stocked tank, having a sump that is 50% of the tank volume would be considered small. Having one of our 30% sumps would just be crazy.
CHOMPERS;2770995; said:The mechanism behind gas exchange is diffusion. Google it and look for the equation that goes along with it. The factors (for solids and liquids) are time, temperature, pressure, surface area, concentrations, and the diffusion gradient. (Notice that "agitation" has no place in the equation.) The bubbles add to the surface area between the air and water, and in fact do increase the rate of diffusion.

I'm seeing the problem. It is in the definition of 'agitation'. I don't remember which dictionary has the dates of usage in it, but along with the dates is an abreviation 'obs.' It stands for obsolete and indicates that that definition is no longer in use. The definition that is no longer in use is the one related to vigorous stiring. The most commonly used definition would relate to ripples across the surface. There are pockets of varying dialects all over, so I am guessing we were raised using the different definitions.heavyhitter;2775708; said:Also take a bucket of water and put a couple drops of dye in it. It will eventually diffuse to equalibrium. Now if you stir that bucket "agitation" dye will disperse faster.
Dr. Joe's explanation is top notch.heavyhitter;2775708; said:So are you saying that the bubbles themselves are oxygenating the water?

this link is the same concept just as a commercial application http://www.youtube.com/watch?v=cFQBMDQIdwQ&feature=related
they only other info i could find was this site http://www.multivis.nl/moving-uk.htm. after watching the videos Like always ended up on here and found this thread. the system seems to be similar and some sort of FBF just without sand. Has anyone here have actual expirence with type of set up? Also the name i've found it under is moving bed filter.
You could be the zennzzo of Bio-Balls.dmopar74;2777300; said:ive been thinking bout trying this, but i hear bio balls aren't the right media, despite the fact i got 60+g worth sitting around.![]()

Now this is where we implement the Kmuda method (from another board). Kmuda, a user on oscarfish.com, is known as the filtration king over there... Just like zennzo is scrubbie master, and JGray12 is practiced in all things FX5.CHOMPERS;2770967; said:Ceramic rings have an indefinite life; the benefit of the micro pores is only good for six months. If you have premium mechanical filtration prior to the fine pore media, it will last longer.
