Lord Walter Northbourne’s book, Look to the Land. Organic farming is based on the ideas of soil fertility, biodiversity, and stopping the use of toxic, synthetic pesticides and fertilizers.

I do not buy into the cosmic spiritual crap, fine if you do, but it sounds much like a reactionary response to mechanization and large scale production of food.
Still, there are good concepts to be found within some of the readings.

Our tanks are small ecosystems.
We can control all aspects without that much effort compared to farms etc.

Can we claim to be approaching things this way and add CO2 at the same time?
I do not think so.

I think the Non CO2 soil tank does however, achieve this goal very well.
Now if you have a solar powered battery to run the aquarium, then you'd be really talking.

It can be done.

I think I'll do a project and use solar powered pumps and light to try a nice tank out using these tenents.
