DIY Aquarium Cover

Why does your aquarium need a cover?

  1. Prevent water evaporation

  2. Acrylic Hinge 10 pk x 2 (Amazon, $8.79)
  3. Clear Acrylic Diamond Shape mini handle for pack of 20(Amazon, $12)

Total cost: $65 to make 8 for (4 x 20 gallon long and 3x 10 gallon), one average $8 per cover


Step by step instructions:

  1. Measure the dimension of your aquarium interior edges.
  2. Cut the Sunlite PC Panel to the size measured in step 1 with table saw. (You can use fine tooth hand saw but a table saw will make much cleaner cut.)
  3. Determine the width of the opening and make another cut across the panel.
  4. Remove the protective film and rinse off any debris or dust from cutting.
  5. Cut out a hole for the airline tubing or power cord with utility knife.
  6. Apply the the industrial grade double-sized tape to a clear plastic hinge.
  7. Attach the hinge to the edge of the panel.
  8. Repeat step 6 and 7 to attach another hinge to the panel.
  9. Apply the double-sized tape to the door knob.
  10. Affix the door knob to the door.
