Introduction: Fish Tank Habitat

About: My full time job as an Organ Grinder keeps me pretty busy but that's just small change. My part time work, as a Mohel, keeps me up to date on my student loans from UCLSD.

  Over the years I have had a several different fish tanks.  As a plumber, I would put any type of mechanical fittings or valves into a tank as habitat.  
  Always having aggressive fish, a ball valve provided great refuge to small fish.  Also, a real mean fish will go after its reflection when there is no food.

Step 1: Materials &Tools

You need a ball valve and a Crescent wrench.  * This instructable is on one type of ball valve. The only difference to the other style ball valve is, you put it in a vice and and turn it open with a pipe wrench.* 

Step 2: Break Down

With the Crescent, remove all the nuts including the packing nut under the handle.

Step 3: The Guts

Remove the handle, bolts, O-ring, and Teflon seal.

Step 4: Position Ball

With the Crescent, position the valve stem to the closed position, so the slot will let the ball roll out.

Step 5: Finished Product

In this photo, I have the ball sitting on the packing nut.  Normally the ball just sits in the gravel. This ball valve is also 1 1/4 but several feeders will fit into a 3/4 in full-port ball valve.
