Hello...

Am very interested in the subject of semi self-sustaning aquariums. Just need to emerse the roots of certain land plants in the tank and add a little aeration around the roots and the plants remove the bulk of the nitrogens produced by the fish and maintain stable water properties.

I'm not totally without responsiblity though. I do have to feed the fish a couple of times a week and maintain the standard filtration equipment, because you need a backup system to work at night when the plants rest. I also have to replace the water lost to evaporation, a few gallons per week for 5 larger tanks.

Attached are some pics of my tank room.
