This just reinforces my ambition to use a fertilizer bottle cap as a planted pico tank. I will probably go with some anubias, an Amazon sword...Oh yeah, and definately some discus.
Two 1 GA desktops, a 5 gallon, a 2.5 gallon, a 10 gallon, a 20 gallon, a 25 gallon, and two 75 gallon tanks, all planted.
I am an expert on algae, so ask me if you have questions. I know how to grow it, just not how to get rid of it.
