First off welcome, I am new here also. wish I would have stumbled on to this site before setting up my tank. I am learning so much from this site it has saved me many hours trying to find the information randomly on the web. Just a bit of FYI, if you want to upgrade your lighting, I did an open 55 gl tank and bought two 48" shop lights in stainless steal for $10 each and use four 48" 40 watt daylight flourescents, for like $3 each and it seams to be enough light for high light plants, and under $40. All at Lowes. This can become a very expensive hobby, so good luck and let me know if you ever find the perfect balance.
