Nano tanks and direct sunlight
Well, the other day I decided to put my 1 gallon acrylic cube to good use and try a setup using riccia (initially) and a window. I then discovered what happens when you take riccia from a fish tank and place it in direct sunlight. It gets irriadiated like bacteria through a UV filter. After one day in the window, all I was left with was white strands that were once my bright green riccia. <sigh>
Maybe next time I will have to start off a little out of the direct sun.
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.
