I had an evolve reef tank up and running for over a year. At one point i had two clowns and a four line wrass as well as a pistol shrimp, asteria snails, and some soft corals. I used the cora life t-5 mini on top of the tank as a light. I'm am surprised looking back on it, that i did not loose any of the fish. my nitrates never dropped below 40ppm and my corals were not healthy. This is a great starter tank, if i may i just want to reiterate what some members have already pointed out... be patient! Im still a nano tank guy but I have upgraded to a 29 gallon HQI biocube and am currently using the evolve 8 as a nurse tank.
