In this instructable i will show you how to make a cheap, and easy aquarium background. I use it in my 10 gallon nano saltwater tank, but you could easily make it to fit even the largest aquariums. Infact, i might even make one to fit my 55 gallon.
Step 1: Tools & Materials
1 Utility knife
or 1 circular/jig saw with a carbonfiber blade, or copper cutting blade
1 tape mesure
1 5 gallon bucket
1 flat working surface
1 greese pencil
1 builders or drywall square
1 peice heavy (40-60 grit) sand paper
1 Sheet of plexiglass 1/8-1/4" thick
1 tube Aquarium Safe silicon. (very important)
1 bag of lava rock
I already had the plexiglass, but i estimate the cost of the materials at under 15$.
