DIY Cinder Block Aquarium Stand
Breeze blocks can be used for more than just constructing buildings. (mason, brick image by Greg Pickens from

When setting up an aquarium, you need a number of supplies, including a tank, filter and aquarium stand. Stands are available commercially that are made to support the weight an aquarium when filled. However, these stands can be very expensive. If you choose a cheaper model, you may have a problem with stability. Instead of spending money on a questionable stand, you make your own aquarium stand at home using breeze blocks and wood that is not only inexpensive but much more stable.

  1. 1

    Use a garden hose or power washer to clean nine breeze blocks. This will clean any debris off your breeze blocks if they are something you have had laying around. If you are purchasing new breeze blocks from the store, this will remove any dust that may have gathered while the blocks were shipped and stored. Allow the blocks to dry completely. This is easily accomplished by leaving the blocks out in the sun for a day.

  2. 2

    Paint your breeze blocks. You can do this one of two ways. The first option is to use a paintbrush and latex paint. The other option is to use spray paint. If you choose to spray paint, you probably will need seven or eight cans of spray paint to ensure you thoroughly cover all the blocks and get into the pits and crevices of the blocks. Allow the paint to dry completely. If you would like, you can paint the blocks all one colour or use a combination of coordination colours. You also can paint pictures or stencil shapes on the blocks for added decor

  3. 3

    Use sandpaper to sand the piece of plywood. You want to remove any rough spots, and this will make it easier to paint your wood. Do the same to your 2-by-4s.

  4. 4

    Paint your plywood and 2-by-4s. You can use any colour you would like. Choose a colour that coordinates well with your breeze blocks. You also could choose to stain if you prefer. Once the paint, or stain, has dried, seal the wood with a polyurethane sealer. This will help protect the wood against water damage. Allow the sealer to dry.

  5. 5

    Cut three pieces of cardboard. The cardboard pieces should be 8-by-16 inches. These will fit underneath your breeze blocks to help protect your carpet. Place the three pieces of cardboard on the floor where you want your aquarium stand positioned. Space the cardboard pieces 8 inches apart. You want the 8-inch sides in line with the wall and the 16-inch sides parallel with one another. Make sure the cardboard is spaced at least 2 inches from the wall to allow for room for your filter cables to hang.

  6. 6

    Place one breeze block on top of each of the cardboard pieces. Lay one of the pieces of plywood on top of the breeze blocks. It will stick out about 3/4-inch on the ends. Place a second row of breeze blocks on top of the plywood. Make sure the breeze blocks are lined up directly above the lower layer. Add the third row of breeze blocks on top of the second, also making sure they are lined up.

  7. 7

    Place your 2-by-4s on top of the last row of breeze blocks. Space them easily to help distribute the weight of the aquarium when it is placed on top. Place the last piece of plywood on top of this.

  8. 8

    Place your aquarium on top of the plywood and centre it over the breeze blocks. Set your aquarium up as you normally would.
