Can someone tell me if this is a good light fixture for a 180 gallon reef tank? This MH ADV+ CF 36Ã¢â‚¬Â is THE reeferÃ¢â‚¬â„¢s light. A space saving combo unit combines 1x 250W HQI metal halide, 2x actinic blue compact fluorescent, and 4x Bluemoon LED into one single unit. This unit also features external HQI controller, heavy duty cooling fans, mounting legs, and anodized aluminum housing. Individual power cords and power switches maximizes usability and timer ready!
