I have many full sheets of black egg crate. so if you are looking to reduce Algae in your frag tank or looking to make your swap tank look sharp this is what you want.
full sheet 2x4' $15 buy 5 or more $13
half sheet 2x2' $10
pick up at my house or meet at lansing swap.
all fellow vendors at the lansing swap can buy single sheets for $13, because i want to see your stuff look good.
