not exactly sure why this thought had not crossed my mind until now,,but i finally removed the glass tops. tank cooled down about 4.5 degrees.
it was 3 deg lower than room temp with fan on sump and fan blowing across 1/2 the top.
not to mention the tank is a bit brighter now, which was my main reason for tossing the things....
