I really like the looks of tanks with real plants. I've been reading up plants for like the past 4 or 5 hours. One formula I got from a site recommened 117 watts for my tank for low-meduim light plants. I don't know if that is right or not. The tank demensions are 36" x 15" x 20". If possible I really don't want to mess with CO2. Some plants I'm considering would be Java Fern, Crypts, Hornwort, Wisteria, Hygro, and a few others. Is there a low cost solution to adding higher wattage to a sea clear acrylic tank? The hood that came with it has a single 24", 20 Watt bulb. Also would running higher wattage risk mealting the acrylic? Thanks for baring with me lol.
