I am going to be upgrading my lighting system from my Coralife 150 watt HQI setup to a higher wattage MH setup.

The question I have for all fellow reefkeepers is what is the best wattage to go with for a tank with a 30-inch depth?

I am housing LPS and SPS corals at the moment and I am planning to go into SPS further in the future.

Also, what bulbs would you reccomend or are you running at the moment?

Thanks

You might want to think about 400's, but 250's with a good quality reflector should work well.

personally I would think 400s would be overkill not to mention expensive to run- I have 150s HQI on my 22 inch high tank and I can keep everything and anything. Although Im not sure if your running single ended or double ended- I have double ended(which to me seem brighter than single ended). Anyway I would say 250 should be enough

I am running De HQI 150's 14K's at the moment.

What type of bulbs and reflectors are you using Marie?

It's just a plain old hamilton canopy with whatever reflector they use (*read* probably not the best

), 3 geiseman 13000k DE bulbs, a 165w actinic vho and a 165w 10000k vho
