The tank is 30 gallons and I have cycled it for almost two weeks. The nitrates and amonia are at 0 and my ph and salt levels are are good. I really like the lighting in many the tanks I see on the forum that make the coral, etc. look purple. I think its the acentic lighting, but if I am wrong someone correct me. If I did get the acentic lighting like ryan said, do I need to keep one of the bulbs I have in now or take them both out and put the acentic lighting in? I just want to be able to maintain the healthiest coral.
