Aquarium Top-off tank Aeration

Aquarium Top-off tank Aeration

As everyone knows, if you let water just stand it, will become stagnant. (and stinky)  To prevent this, you need to stir it up occasionally. In the Aquarium Project top-off tank, I’m doing this by aerating it through air stones connected by tubing with my air pump.

To do this I drilled a one quarter inch hole in the tops of the top-off tank caps and thread some silicone air line tubing through. Then inserted  a piece of hard line into the tube and lightly hammered it down to wedge it into the cap. I then attached a one way check valve towards the top of the cap and an air stone to the bottom of the tubing. This check valve prevents water from flowing back into the airline and down into the pump when the pump is off.

I do have to confess something…I messed up!  I got in a too big of a hurry trying to complete this task, and ended up gluing one of the tanks together before I realized I hadn’t inserted the check valve in it. So…now I have one tank with the check valve in the air line outside the tank. It will still work, but just is not as cool looking.
