Here is a calculator
that Scott Morell has developed to assist you in building your own
"Low Profile" aquarium canopy. The low profile canopy is between
7 and 14 inches tall and an option to have the back open or completely
closed.
All you need
to do is enter the actual length and width of the tank and the height
you want the canopy. A materials list will be calculated and displayed
on the following page along with assembly instructions.
Disclaimer:
Construct these canopies at your own risk. The authors and Idaho
Marine Aquarium Society will not be responsible for any damage or injury
caused by improper construction. The combination of wood and
water can lead to serious consequences, so please use common sense or consult
a professional carpenter if you do not have the proper experience.
