Bought as a tank with a bulb in it, replaced by a way too powerful ledbar but now outfitted with a Juwel Novolux 5watt LED tube.

The CO2 system is a small nanostyle Colombo kit, with a aquaflow 100 filter.

After a burst of algea in this tank and replacing it with the Novolux, this tank is doing fine! It was my second aquascape, supplemented after the needle grass settled, with a bonsai with javamos which started in the 20 liter. The Sakura red-cherry shrimps love cleaning it and the Cardinal Tetras seem to do fine. Tho the tank is really too small for 11 of those guys, they seem to do fine.
