Yep, I am still thinking and thinking how to improve the efficiency of a closed aquaria system.
Here, I was just reading the latest issue of Aquaponics Journal where scientists has been building anaerobic tanks to help digest waste (liquid and solids) from the pigs and chicken farms. And as the anaerobic bacteria fixed NO2 and NO3 back into O2 and free nitrogen, the nutrient rich water is fed back to a algae pond.
This is somewhat what we all have been trying to achieve thus far as well with DSB and refugium.
I want to take it a step further. Remembered that the discussions of building live photoplankton reactor? One of the problem is the water being used. We have been discussing about passing the water through UV tubes to kill off any pathogens and microfauna that could wipe out the algae culture, but still fear that if anything survives, the culture would be wiped clean. Well, I think we can try passing the water through a anaerobic chamber first (or 2 of them in sequence). All living free floating organism would be dead passing through the anaerobic chamber, leaving the water nutrient rich and microfauna free. Aerating the effluent will kill off the anaerobic bacteria and the effluent can then be fed into the phyto culture chamber. This way, nothing in the water is wasted and a complete closed system "could" be achieved.
The system can be completely run by itself with just a dosing pump to regulate how fast the flow through rate be. The phyto can then be used as is or be connected to rotifer or artemia chamber.
What do you guys think?
