I do have their MH system. The 1070 watt, three X 250 MH and four X 80 T5's. I love it. I started out with two of their 36" fixtures over my 72" tank. When I upgraded I kept one of the old 36" fixtures (one 250 watt MH and two 96 watt PC) for a 30 gallon breeder that I have in my basement with hopes of one day setting it up as a nano reef. When I first got interested in keeping corals I wasn't sure I would be willing to risk a $1,000+ investment on a fixture for a hobby I wasn't sure about. When I was ready to upgrade I considered the growth I had with their product and gave them more business. Now that I'm considering a tank upgrade, I'm looking into more expensive LED fixtures or a DIY LED. I'm glad I went with the fixture's I've had because up until now I didn't know how much I would really like this hobby and therefore didn't know how much money I'd be willing to throw at it.
