UNS 60L, with monte carlo carpet, red crypts, hydrocotyle, weeping moss, and salvinia minima. Terrestrial plants are some kind of scindapsus, syngonium, pothos, dragon's tongue, and a heartleaf philodendron, some of which is growing in a HOB with filter media removed. No CO2. I haven't done a water change in maybe 4 months now.
Stocked with crystal red shrimp, some orange neocaridina, pygmy cories, and ramshorn snails.
I like your setup a lot. I been thinking of doing a shallow tank and I really like the idea you got going here.
I find almost all plants don't like a ton of water flow which is why I was curious about your filter and flow setup. That sounds perfect to keep the top skimmed but it won't off gas like a sponge filter will starving the plant's of co2.
