Hmm...I thought I had ordered Sunset Hygro from Aquariumplant.com, too. As it turns out, doing a little research and picture comparison, I DO in fact have REGULAR hygro! I'm not sure if they sent me the wrong stuff, or if I just changed my mind at the last second and decided to go with the regular H. polysperma, rather than the sunset. I will check when I get home, since I saved the original order and folded it up and put it in the canopy of my tank, just so I remember what I originally intended for it.
Edit: Okay, I looked up my order on Aquariumplant.com. As it turns out, I did order regular H. Polysperma. I think I must've been wanting a green background plant at the time. My original concept had a LOT of reds and pinks in there, but due to having to turn the lighting down a little, it now has a LOT of green in it, hehheh.
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.
