I would like to introduce my Dutch tank. It's planted in Feb. 2008 and there have been a lot of changes since my first set up.
The tank dimensions are 120x50x50cm.
Lightning: 6 18 watt T8 840 TL's and 1 30 watt 840 TL. together good for 138 watt.
I used simple sand on the bottom of the tank.
co2 30 bubbles per minute and some fertilizers (Profito, easycarbo, No3 and Po4)
