Hello. I am an experience aquarium guy with a 75 gallon fresh water and considering upgrading to a 125 gallon fresh water tank. 15 years ago, I had a 15 gallon tank and had extremely good luck with plants, but have not had any luck with the 75. I have heard that I don't have enough light for my 75 (a single 48" fluorescent bulb). The recommendation that I have received is 5 watts for each gallon for plants to do well. If I made the new purchase, I would like to have it set up to have live plants along with the fish. Does anyone have any recommendations for wattage or lighting systems? Any advice would be appreciated. Thanks.
