| Re: 1000 Watt Mh-$100---? I have kept sps corals and in particular acropora and montipora{plating type} for 9 years now and have never used anything more than a 250w halide. I have a 120g and have 2 250w 10k reeflux and have all the growth and color you'd ever want in a sps tank. 1000w halides are not needed to keep these corals. The most important thing after lighting is keeping the water stable for calcium, alk and mag. After that they grow like weeds. |
