Wasn't happy with the brightness of the light that came with the new set up I bought (Aqua one 300) fluval reef 200. Invested in 2 viparspectra 165 watt led lights. Brightness was something else, so much so that initially I've dropped them down to 30% intensity on both channels. Easy to program with built in timers, the thing that impressed me most was the colours I saw tonight when they switched to blue only. The various polyps I have all looked the same before. Tonight I've seen red, purple, orange in them. Mushrooms showing red rings around there edges. Common clowns appeared more like tomatoes lol. Very pleased with them.
