My daughter have a 54 liter dirt tank that runs amaislingly well, it have only a thin layer of dirt and a thin layer of fine sand. Plants are growing like weed, a couple of weeks ago i did remove about one 10 liter bucket with plants, the tank was totally overgrown. The tank runs with almost no maintance at all, i have only changed 20 liter water and done one filter cleaning in 7 months.
That was "one filter cleaning in 7 months" not water change Still pushing it a bit with the fish load.
Sorry about my bad English, i meant one filter cleaning and one waterchange in 7 months. Both was done at the same day.
I think the plants is doing the main filtration job, the tank have had a massive growth, the picture is after a massive cut down and replanting. The fish load seem to be no problem, i think the plants is taking care of them
It looks very nice. I've just recently set up a dirt tank as well. 80 gallons (or about 300 liters). I could only dream that it might ever be as low maintenance as that, though.
How are those mosquito fish doing with their tankmates? In my experience, they've been pretty aggressive with other fish in my tank - but then again, I've never kept them long enough to see if they'll settle down just because of the aggression.
