I have a 29 gal marineland eclipse saltwater tank. In it I have 3 anemones and about 10 mushroom corals and a couple ones from the wild. The tank they were in before broke so they got transferred into there currently I have a 15 watt actinic T8 bulb and a 15 watt 10,000K T8 bulb. Is that the best I can do without going to metal halide or is that the best I can do for corals.
