On what kind of lighting to use on a 180 gallon tank. I'm thinking 2 6 foot VHO's and 3 Metal Halides. I've never had halides on a tank so I don't know much about what wattage rating to use or kelvin temp. Any advice is appreciated. Thanks.
I have a 6' long 150 with 2 6" actinic VHOs and 2 250w 10000k aqualine MHs, running off of an icecap 660 and 2 hellolights.com electronic MH ballasts. I grow stonies like some people grow algae with this set up
