A month ago, the cube garden was a disaster, overrun with a stubborn algae the otos couldn’t keep up with and rotting fish food because I hadn’t yet figured out how much the neon tetras were eating. Cleaned it out. Cut out the plants that were algae-choked, replanted with micro sword and glossostigma, recharged the DIY CO2 and moved the whole system back into the kitchen where it won’t be neglected. Now it’s positively glowing. Seven gallons of planted tank heaven. I love this little set-up because it’s my first aquarium, purchased almost three years ago. Beautiful, simple (well, complicated but in a good way) and makes me happy.
