FYI im getting it for 42.

WOW WOW WOW your telling me 430w of light isent enough. If you missed it I have 2x 175 w MH and 2x 40 w actinics.

430w of light =9.3 watts per gallon.

$42 for a 6055??? Sounds is a little to good to be true.

And following your tank journal thread it's clear that your tank is far too new and unstable for SPS.

And yes, you won't get the most out of SPS with 175s. They'll stay alive and grow, but they probably won't have eyepopping colours. It has nothing to with WPG.

You don't need a Ca reactor for a 46 gallon tank. You'll get by fine dosing 2-part.

Yes but 2x 250 watt MH is over lighting and I don't need to burn my corals. 1x 250 w mh wont work either because I have a stupid bar running down the middle of my tank and I would have a "eclipse" effect.

Well i know wher my money os going now.

If a coral is sitting 5" away from a 250w light in a 500g (0.5w/g) tank it won't be any happier under a 40w light in a 2g nano tank (20w/g)

I don't get it Marie.

Ok then look at it this way, If you took a gallon jar put some rock and salt water in there and placed a little frag 5" from the surface of the water and then hung a 5 watt christmas light over it the frag would be getting 5watts per gallon of light.
Now if you took a 500gallon tank, with rock and saltwater, frag 5" from surface and hung a 250watt light over it, you have 1/2 watt per gallon
Which frag is getting the better light?

Marie's post is missing a ?

She's saying that watts/gallon is not a very good way to know how much light is enough. SPS like high light, high flow, but stable, low-nutrient conditions, which is very hard to achieve in smaller tanks that are new. SPS should be kept in more established tanks after all the nutrient levels are stabilized. New tanks often have fluctuating nutrient levels which will brown out SPS & often lead to death.

The one in the jar? I think.
