Antoher lighting question... Sigh...

[fortheloveofcrabs]

I've never seen a 'for sure' answer to this, so I going to ask it again. Is there such a think as 'too much light'? For example, I have a 55 gal tank, and I am upgrading to MH... Now originally, I was going to go with 2 250 watts, but 400 watts are pretty much the same price. Now, heat and cost aside, is there any reason NOT to go with 2 1000 watt bulbs?

I remember when I entered this hobby, 8 - 10 watts per gallon was 'where you wanted to be'. Is this still true, or is a more the better game?

After all, as a fellow reefer said, 'In nature, these corals are under one big @$$ bulb'.

Thanks.
