This is what works on my tank....I do about a 20% water change every 2-3 weeks using Brightwell salt to replenish trace elements. I have a lot of cross flow in the tank. The return and Koralia 1400 blowing down the length of the tank and then using a MP40 and MP10 for cross flow. Lighting is T5s and MHs. My preference for light dispersion. I use mangroves to remove nitrates, phosphates, and toxins. I feed with coral frenzy 3-4 times per week. Corals are happy.
