Air in My Fish Room

Following the basic pattern shown by Ted Judy, I created a closed loop using 3/4" PVC. I chose to glue the pieces although Ted Judy says it is not necessary.

For air, I'm using an Alita AL-6A Linea pump. The Alita comes with a screw-in adapter to which I attach a length of 5/8" (inside diameter) tubing, and the other end I used a 3/4" adapter with a metal nipple on one end and the other screws into the PVC.

I hope the video demonstrates all of this.

Also shown are the tanks/sponges being driven by this arrangement. This is the smaller Alita, but it has plenty of air to spare, I have one air stone not submerged, to bleed excess capacity.

Looking good, Mark.

With all that air, you now need more tanks! :FIREdevil:

Thanks I'll add this to my plans. Where did you find Ted Judy's plan?

There are several, all good.

I'm using the same pump, but with the provided manifold instead of a closed loop... should I be bleeding this too? What does this do for the pump?

Ted Judy indicated that the closed loop helps build and evenly distribute the pressure and air. A straight line was suggested to affect the pressure.

I have to bleed excess or else the pump makes a buzzing.

On the loop I use the Nickel Plated Valve which requires the thread tap (both from this page http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+3669+8165&pcatid=8165) Then I had to find on-line a Q drill bit. Ted Judy demonstrates how to do the valve installation in detail.
