What I meant by false colors is that normal glass is a heavy tinted green...unless you have starfire glass. Just look at the end section of your glass and see how green it is..... My glass is standard plate glass, which most tanks above 125 gallons are. It turns your green clams to blue clams, it turns some blue colors to shades of purple, it dulls the whole scene of a tank when compared to starfire glass or of course an acrylic tank. To see what you are missing, borrow a kids swimming mask or an acrylic viewer and peek from the top of the tank through the water, then look through the glass. If you dont have Starfire glass or an acrylic tank, then you are seeing everything through green tinted glass, its as simple as that.
