I have finally got myself an Aquamedic Aquasunlight 2x250w, 4x54t5 unit. The 250w is Aquamedic bulbs and the t5 Giesemann. Im hoping to get colour like yours thats my aim. I want to try the NP pellets too. What kind reacter are you running the NP pellets and the pump used? Also what brand NP pellets do you use? Your tank one of my all time favourites, keep up the good work man.
