Anaerobic Bacteria

If all you need is carbon, why not put in some driftwood instead of dosing? That is what you do when you need carbon in your compost. I have never taken chemistry, will do so for the first time this September, so much of this went over my head, but this seems obvious to me.
 
The coil method that was mentioned in this thread intrigues me. What if you had a large enough sump you could run a massive coil of PEX piping inside of it? I would think if you ran the coil externally somewhere you would have lots of heat loss and thus not be worth it in regards to energy consumption vs just doing a water change.

Many woods will leach "tannins", or plant phenols, into the water. You are right that these chemicals are DOM and also DOC (they contain carbon). However, plant phenols exist in plant tissues to aid the plant in maintaining it's tissues. Plant phenols are resistant to breakdown via REDOX reactions because their role in plant tissues is to do precisely this... to prevent REDOX reactions. In other words, they are commonly anti-oxidants when found in plant tissue. As a dissolved component of your water, I would not consider them a good electron donor for denitrification.

It intrigued me too (atfirst) but im skeptical atleast for large tanks with high bioloads.

This guys claims its a success but what good is getting 0 nitrates out of the filter when your getting nitrates in the tank. Granted im not sure what his readings were prior to the filter but i just cant imagine something thats dripping 1 or 2 drops a second would outperform the bioload that big fish are producing constantly.

I'd imagine the nitrate creep would outperform the filter.

The coil I mentioned goes inside a PVC pipe or whatever, so that it can run to more densely packed media.

I really have to discuss this with the prof.

The one I have in mind can run after a canister filter or bio media in the sump. Full flow, but won't work if the o2 is removed by the media


Am I missing something? Is there a biological AND bacterial way or something? I'm a bit sleepy

I'm not very well versed in the "coil method"... I have no idea what it is all about. I am very happy to see that you have fallen in with good company, who I assume to be a professor that is familiar with aquaculture. From what I have seen of your posts to MFK I think this might be a very productive and good relationship for you :)

Biological and bacterial filtration is the same thing.

now at least I can say something intelligent. :) if one coil can't keep up with bioload, add another. They don't effect each others effectiveness, as we have seen they will work all the way down to zero. If a lone pearsei needs a coil, a large SA/CA community can work with ten. IMO, the best system on a large scale seems to be a large bucket of sand with a low top to bottom flow and the ability to clean by pumping backwards doing mech bio and denitrite in one long pass, say 75gph, with circulation pumps in the tank.
For me, I'll stick to my aquaponics and beat every denitraror and every algae filter every time :p
Hendre Hendre , I am jealous of your professor. great find! :) ;)

I summarised it earlier in the thread :)

I believe so as well. He helped me with ways to culture infusoria as well which I have started for my tetras eggs :D
(Plus he is practically the manager of agrisciences at the university)

Aquaponics won't work for my planted tanks lol

Thanks :)
 
I have a planted tank, too. No room for aquaponics or denitraror there. WC :(
