Color Change In Dsb???

[tdog7879]

Is it normal for the DSB to have different colors in it or is this a problem.
COLORS: GREEN ON THE TOP JUST WHERE I SCRAP THE GLASS
ALSO HAVE A REDDISH COLOR IN SPOT AROUND 1-2 INCHES DOWN
I HAVE BEEN SEEING LITTLE AIR POCKETS HERE AND THERE ABOUT 1-2 INCHES DOWN.
ANY INFO WOULD BE GREAT!

That's probably algea starting to grow, its not a real problem, it just looks ugly once it spreads. I have corealine growing like that, which make sme think that my dsb, is not really a dsb.

i knew sb was sand bed but "deep" never came into my mind.

and yes, that is normal, i have different colors in my 2 inch sand bed. it only grows on the edge, because light still gets there from reflecting in the glass. it doesnt grow under the sand.
