Aquarium lighting is very important in freshwater and saltwater tanks. In the saltwater reef tanks your corals need proper actinic bulbs and 10k bulbs for ideal growth in your aquarium.
In the Freshwater aquarium and planted tank the general preference is 6500 k to 6700 k with power compact lighting. This is the general bulb color people choose for growing freshwater aquarium plants.
Replace the power compact bulbs in your freshwater aquarium every year.
Replace all saltwater bulbs in your Saltwater - reef aquarium every 6 month for ideal coral growth.
