How to clean a Built in Aquarium.

For cleaning this tank you open the trim at top.

Cleaning a fish tank in your wall is basically the same as cleaning a tank outside your wall.  The only difference is that you have less elbow room.  First you will have to gain access to the top of the tank.  This is typically achieved through the top piece of trim.  The trim flips up on invisible hinges or lefts off with Velcro etc…  If the backside of the tank is not finished you can leave it open at the top and access it that way.

Once you have access maintenance proceeds like any other tank.  You will remove around 1/3 the water through a siphon tube.  While you are sucking the water out the waste in the gravel should be removed.  When the correct amount of water removed replace it with tap water and some water conditioner.

The tank does not move and the fish do not come out.

Electrical around aquariums

Disclaimer: Although I have a fair amount of experience with electrical work I am not an electrician. You may need a qualified electrician to do the electrical around your aquarium. Check your local by-laws.

To prevent any shock hazard you should install a GFCI outlet. This is the same type of outlet you’ll find in your bathroom.   A typical aquarium will have a light, filter and heater. Some larger aquariums like our Jumbo Wall Aquarium has 2 lights and 2 filters and a heater. This means that you will have 2 – 5 devices that need to be plugged in.

Your outlet should be concealed inside your wall opening in one of the top corners. Make sure not to install it in the top center, it might interfere with the lights placement. Once you have one GFCI installed you can wire additional outlets off of it that will have the same properties (refer to the GFCI’s instructions). A second outlet in the opposite corner will be useful for larger tanks with extra devices.

  • Aquariums look much much better inside a wall
  • Wow factor
  • You can look through the wall
  • Take up no floor space
  • Improves a rooms decor


  • Less elbow room for maintenance
