Yes the MH light is awesome. I had the red sea max for a bit until I sent it back and got this one. Now I can compare.The max looks better by far. But with things like the light, the wave maker, the 4 moonlights, etc, so far the nano mechanically runs better. I will have to give it more time but the flow is better than the max being it has 2 nozels instead of one. I bought a chiller because I read up on this alot before I bought it. With these lights I would need a chiller. I have it on a constant 78. I had the lights on for 8 hours today, it never went past 78 all day.The max never went past 81, but I have my a/c on 77 all summer. The max just did not run right. The biggest problem was the skimmer took alot of the flow away. And the skimmer never worked right.Overall I can tell better in in few weeks. I will let everyone know.
