Thought it might be interesting to know how much light people are using, not just illumination hours but actual power.

I am using 4 30 watt tubes at the moment to illuminate a 180 litre tank.

Anyone else care to share what light they are using?

I'm doing about 1.5wpg on my 125 gal, 1 wpg on both my 20 gallon longs, although I'm looking to upgrade one of them to 1.5 wpg in the near future.
