Today I have set up my first ever planted tank it is low tech 20"x20"x24" with a pond soil substrate topped with sand, light is a beamswork 10 x 3w which if I have my calculations correct works out around 0.7w per US gallon, will this be sufficient being that the tank is 24" deep or would the addition of another unit the same increasing the total to 1.4w per gallon be preferable?
