This tank is so far working better than i expected just with sunlight and airstone as the only tecnick.
But i would like to enjoy this tank at night when the sun is gone also.
Is there any way i can light this tank at night just to make it nice to look at? I am afraid that artificial and the sunlight will lead to algae. I actually need a reccomendation for a light that not will effect the tank in anyway, just be nice to look at? If sutch light exist.
