Lighting question. Please help
I have a 48" 55-Gallon tank with a few New World Cichlids. I recently added a some anubias, java fern, anacharis, and christmas moss. I want the plants to grow in well and potentially add a few more plants. I have a Coralife T5 HO light fixture which can handle two 48" 54W bulbs. However, I only have one 10,000K bulb in for fear two bulbs will be too much light and cause excessive algae growth. Please let me know what you all think? Should I leave it as is, or add another bulb, if so what kind do u think? What about adding a 50/50 bulb? Needless to say, I have no desire to add any forms of CO2. Please advise.
