I have a 50g tank moderately planted that houses my ruby red spilo. There is a decent layer of duckweed and water cabbage on top of the tank. I am not sure if I have enough light. I am running one coralife T5NO dual bulb 24 inch fixture with a 10,000K and 6,700K bulb and one standard dual fixture with two T 12 bulbs. Do I need more light? should I switch any of the T 12 bulbs? Thanks
