I recently got an outdoor shelving system from IKEA to put some potted plants... as usual i ended up filling the extra shelves with aquarium-related items too. :)
My original plan was to just use a normal planter box for terrestrial plants, but then i remembered that i had a spare low-profile glass tank (L40cm x D25cm x H18cm) that was able to fit nicely on the shelf, so i cleaned it and filled the bottom with a simple sand base, then planted it with Anubias Barteri var. Angustifolia (glued to individual small rocks) and further surrounded with more rocks.
Filtration and oxygenation is supplied by a small sponge filter (its sitting just behind the plants).
Some of the anubias plant leaves currently poke out of the water surface but parts of it are still underwater so the leaves are kept hydrated. Hopefully by the time the leaves start to grow taller out of the water they should have adapted back to emersed form.
No fauna at the moment... though i'll probably add in a few small hardy fishes soon to prevent mosquito breeding.
The tank is positioned in a shaded area and blocked by other plants but it still gets indirect sunlight for most of the day.
With slow growing plants in a full glass tank outdoors, i guess it'll probably be a count down to algae fest in 3... 2... 1... *fingers crossed*. :)
