Hi there! I wanted to show you my current projekt, hope you like it. The photo is isn't the best. Next time it will be better. The tank sizes 40x28x25cm, total volume is 28l. The lighting is self made with 2x9W G23 lamps, to circulate the water there is just a little pump with 150l/h in action. Pressurized CO2, daily fertilization. My english isn't perfect so i'll not write down here everything about the hardscape, plants, and so on. If there are questions just ask, i'll do my best to answer them.
