How awesome is a tank built into your wall?


This is a silly post however, if you are thinking of adding an in wall tank to your house, it’s because they are really cool.  A normal fish tank can look nice and clean but a tank in your wall, one that you see-through between rooms is georgeous!  Guests first response is one of shock and amazement followed by a guess at the cost.  When you tell them that a tank like this costs one-tenth of what they thought and you did all the handywork yourself, they have a new respect for your abilities and think of where they can add one to their home.

Java moss, an easy aquatic plant.


Java moss has gained popularity with the aquarium hobbyist however it is difficult to find in a pet store.  It’s surprising because Java moss requires no special lighting, looks amazing and grows in a variety of water conditions.  Shrimp (another recent favorite with hobbyist) and fry love to hide and eat algae off the moss.  It can also be used to make a moss wall instead of a backdrop and it improves your overall water quality.

So, I recently purchased some, not from a pet store but from ebay:

Surprisingly it can be shipped without dying but from the ebayer’s feedback it looks good, can’t wait to put some up!

Running electrical for a tank inside your wall

Obviously your in-wall tank needs to plug in somewhere to run the lights, filter and heater.  First, any outlets around the tank should be GFI (ground fault interrupt).  This is the same type that you have in your washroom.  It will prevent any shock hazards from the water in the tank.

This outlet should be inside your wall opening so you do not see it when you are looking at your tank.  Typically it will be hidden under some trim out of view.  If your opening is tight do not place it in the top center.  It might get in the way of the light (the top corner is preferred).

3 – 4 devices will run off of this outlet so either a double outlet or  power-bar will be required in the end.  Any wire slack can be stapled out of the way.  Do not worry about seeing the wires off to the side, when you look into the aquarium the ends inside the wall will reflect the light inside the tank like a mirror.
