Advice? Revisiting old ideas......

Hello GIRS!!!

New member here, first post. Don't brutalize me!


I fantasize all the time about what I think may be innovative ideas, to find out they may or may not have already been tried. I know many dreamers like myself and I propose a "gathering of the minds" if we could.

BIOLOGICAL FILTRATION: We have reused every form of wet, and dry filtration imagined. We have combined many. Bio pellets, ceramic rings, LR in the sump, DSB, bare bottom tanks! We have done it all.

Tonight I want to ask about FBF or, fluidized bed filters. Basically a calcium reactor used for converting massive amounts of ammonia into nitrite, and less toxic forms. The only problems is, once they become so riddled with bacteria, it can cause a crash. Similar to all of its previous forms.
The greater problem with this type of biological filtration was phosphates are consumed as well, again, once capacity is reached cause a spike.

Why don't we just connect them directly to a skimmer? As the bacteria die off and purge, the next line of defense will immediately remove said undesired proteins. Combined with aeration (if done properly) will help maintain a steady pH taboot!

I also once heard tale, of quite the opposite. Instead of tumbling the media for maximum surface area, the water was forced through a vast DSB of sugar fine sand. This was enough to pre filter any large particulate, offer plenty of anaerobic bacteria for denitrification, and because the bed was so deep no protazoan was fine enough to pass. Essentially, we could make a 99% parasite and nitrate/phosphate free water. Does this theory sound fanatical or legitimate. Has anyone else heard of this. Are there any biological engineers present that could input on the "desired area" necessary? I wish I could find half of my old readings.....
