I have a 30 gallon planted tank with a 98 watt compact florescent light set at 12 hours per day. I have some vallisneria that i have to uproot all the time because it grows too quickly. Other plants are doing well too. Except I think the java fern and anubias could do better. I'm wondering if I should cut down the hours on the light since I am finding some hair algae in the moss and a bit of algae that keeps coming back on the glass, even though I have emergent plants. I am starting to think that there is too much light. I have other plants as well.. some hair grass, a melon sword (which keeps shedding leaves and growing new ones-is that normal?), hygro, and some others. Will it still work out with less than 12 hours of light a day? If so, how much can I cut down the hours?
