sunvalley aquarist;4796368; said:You might be sorry with black background. I wanted black background and black sand in my 240 when I set it up thinking this would make my fish stand out. I had to settle for gray background and black sand. Now a year later, I'm changing to white sand. My fish have darkened considerably, and my lights don't light the thing up that well during the day. At night the tank looks great but the fish (Discus) are DARK! I could put in more lights, but lighter sand will be cheaper, and I won't have to worry about increased algae growth.
thanks for the heads up. Do you have any pics of the grey background and black sand?
