I have some DIY projects in this that are detailed in the link to the original thread. They Included a paintball tank style pressurized CO2 system that I am very pleased with and a DIY light fixture made from a piece of stove pipe.
The tank has been running smoothly for another 2 weeks or so now and I thought it was time to post an update.
Turns out, if you bombard a tank with a butt-ton of Light and CO2 plants grow like crazy!
The pics are from a camera phone so it is hard to tell but the ludwiga has doubled in size and the HC has probably done about the same. The Narrow leaf micro sword is a different story, I don't know if it is a notoriously slow grower or the roots are having a tough time taking hold. I added some flame moss as well.
