yes I was jesting a lot.. I did forget to mention you can get true color out of any lighting also but it is not as common under lower intensity lights like VHO, PC, T5, ect.. this is where the being extremely picky and selective with your corals comes in.

I do have one problem with that link you posted.. it is a fauna marine add. they didn't show out of tank photos before the test only after, so we have no idea on the quality of the corals before the test so I can not look at that pdf and consider the whole thing valid. plus if thee is one thing I have learned in the last 8 years is to take any advertisment with a grain of salt.. do they want to sell there products... you bet so if they can make there product look a bit better will they... you bet.. now I have nothing against Fauna marine personaly (thought I better make that clear) I am going to be buying there proflux, and I wish they would staert putting out some nice colored MH bulbs.. like maybe a true 12000K color temp 250 watt SE

Steve,

Fauna Marin isn't equivalent to GHL Profilux - they just happen to be distributed by the same North American distributor (Aqua Digital). So you can criticize Fauna all you want without criticizing GHL.

And I agree about the pics being an add but they were the only ones I knew of off the top of my head that included underwater and out of water pictures of SPS grown under T5s.

ah good to know I thought they were one and the same. but I am not critisizing, just stating that I cannot accept a company's add as proof. thats why we have places like consumers reports and such
