    If you are using proper reflectors, there is no need to paint any specific color because the bulk of the reflective light would be directed towrad the tank. Stray light which may be withing the canopy is neglagable, but if you want everything as reflective as possible, piant the inside white.

    The matt white or gloss white is still on strong debate. The reflectiveness of white is about as good as it gets (next to a mirror finish like polished steel or actual mirror), black is the complete opposite in that it absorbs light.

    Chrome vinyl is worse than using tin foil, and as tests have been done with tin foil, unless it is PERFECTLY flat which is not possible, it bursts the light into so many different directions that is's actual reflectiveness is not suitable to achieve the results we require in a marine environment.

    White absorbs no light and reflects it all. Some say it is even better than mirror polished steel.

    I would say gloss as the reason matt looks more dull is because the surface is rough and it disperses the light over a larger area instead of concentrating it.

    There are some threads already posted om MASa about a week back showing a full technical analysis on reflectiveness of white and it was adebated than without result if gloss or matt was a better choice. In the systems we are running, the small losses you might experience using either matt or gloss white is neglagable. Considering it is simply a coating inside a canopy...
