I have the 130 PC 50/50 for my low/mid tech and like it. Although there is hear-say that the bulbs only put out 55watts instead of 65, giving you 110 instead of 130. Whether that's true or not, I've had good results. Just stay away from the 50/50 bulbs that have "Actinic" light. The actinic does not do ANY good for aquarium plants.
