    Ive always wondered if I put air into my BD, would that force more water to flow through it? I am thinking about sticking the hose end from my hiblow 40, with no aerator, into my BD. The air would escape from my sieve prior to reaching my filter and pump. I'm thinking it'll push more solids through, preventing settling and clogs as well as aerating the water prior to reaching my filter, giving more oxygen to aid that process.

    If there is an upward slope in the bottom drain pipe, you may be able to do it. But the nature of air being what it is, it will only stay on the upper portion of the pipe all the way to the filter, never even touching bottom to clear the debris.

    In the video, Bjorn says the size of the holes where air comes out into the waterlift is from 0.5-1.0 mm, depending on...
    I would take the hole size as being ones that would create the optimum bubble size to bring the maximum waterlift. What do you think?

    Yep! That's probably about as small the bubbles can be via this method. You have to go to air stones to get much smaller.

    Here's a video by Patrick (here he speaks French) showing how the pressure chamber is made:

    You can get the idea even if you don't speak French, but if you do, did they mention the size of the hole drilled by the Dremel?

    Use the video linked to in the first post, it says the hole size is .5 mm or 1 mm. Fast forward to 4:55 mark. All in English.

    Now that we got the hole size, how many holes? Got to get that right since it would be hard to add more holes. Glued in by then with PVC cement.

    Hmmm... I will have a hard time finding these in Manila. A nominal 4" sanitary pipe, a corresponding coupling cut in half, and maybe a PVC roof gutter adapter I saw at an Ace Hardware store. Cool! Now to get a collet to drill those tiny holes.
