I decided to go ahead and make that DIY fixture and added another 56 watts to the 65 watts from the coralife fixture. This all for my 40 hex. Then I went to petco and bought one of those cheap co2 setups by Jungle (much like a DIY setup). I did all this within the last 4 days, and my plants are growing like crazy already. Before I did all this, my wisteria looked like poo with the broad leaves and now it's getting those beautiful lace like leaves. Oh, and my java moss is out of control now. I'll probably post some pics tomorrow. Thanks for all the awesome advice everyone! I couldn't have done it without you.:thumbsup:
