I know of that fog machine! It is awesome, it utilizes a small vibrating disk that induces water vapor as water is fed to it (ultrasonic)
many companies make them, the one I know of is from Azoo and found at
www.aquaticeco.com
The planted bowl is by far the most stable pico I have. It goes 3-5 months in between water changes and uses absolutely no circulation. Nitrogen and nitrates are provided by one single dwarf frog, fed bloodworms regularly. This system is over two years old now, the oldest pico I have. It houses about 10 species of common aquatic plants and also a few malaysian snails for added diversity. Convection is induced in the substrate bed (flourite) via a small candle warmer, the vase sits on it and this acts like cable heating commonly found in the large planted tanks. I drip fertilizer in it once a month, and it is fully capped with a lid and also has no evaporation.
Not every planted system needs mechanical circulation... tiny amounts of fertilizer become equally ditributed in time from action of the frog, and from complete dissolution into the water. The single frog is an ideal character because he is not reliant on water column oxygen, so the night cycle is no problem. His protective barrier skin is unharmed by nightly pH fluctuations caused in dark phase photosynthesis, so the bowl stands alone in support. He does contribute to tiny motions in the water column, everything works together and is easily maintained.
One tunes a pico reef by distorting biological ratios, thats what I always say.
The terrarium has a substrate zone that catches water percolating through the mudbed, and then feeds it back up to a small driftwood waterfall via a minijet pump hidden under the soil. Space for air is accounted for in the drip zone to keep the water clean and oxygenated. This system is fed water out of my 75g every once in a while to refresh the nutrients.
Gracias Brian thanks for checking them out
