A small Walstad nano aquarium with crystal clear water. Female blue betta fish swimming in the middle, vertical driftwood with hanging Anubias plants, Cryptocoryne on the bottom, Salvinia floating on top, leaf litter on sand substrate. Low-tech natural setup.
Just set up a small Walstad nano a few days ago. Dirted soil under sand, leaf litter, old filter media from a mature tank. Water crystal clear already, female betta loving it. No CO₂, no fancy lights, no water changes planned. Old school way – letting nature do the work.
