  1. Now that is a good idea. Eliminating the need for air stones is a big help.

  2. That’s a great set up Dale.. Would work great in a large aquarium too
    methinks.. Are you going to give DWC a crack with one of these jobbies?
    Thanks for the mention sir..
    I give this one a wet & bubbly thumbs up ;)

  3. Nice demo. I saw one a while back where it was so powerful that you could
    no longer see the fish, lol. He didn’t leave it on though.

  5. Very nicely demonstrated Dale… I’m fascinated by how this works… I love
    the fact that air can be introduced without the use of addition energy
    :-)… Thanks… Chris

  6. Looks like its putting out some nice air & circulating the water really
    well. I think it would work great In a DWC system. You didn’t test that out
    in the kitchen did you. I pictured you having the tube going the wrong way
    & spraying down the kitchen-LOL.Well done on the video- you had some great
    footage in there. Thumbs up for Ricks comment !!!!

  7. I’m going to have to stop watching hydroponic videos or I’ll end up with a
    garden full of IBCs.

  8. I wonder if using a standard aerator for a sink would break up the bubbles

  9. I tried something similar a couple of months ago, but sadly a hopeless
    algae issue popped up in the fish tank. I belive the aquarium received too
    much light.
    Hope you get better luck with your project, than I did. :)

    Best wishes,

  13. I recently watched Rob Bob’s (bnbob01) DIY venturi video and it looked like
    so much fun I thought I’d try my hand at making a small version out of easy
    to find local parts. I hope to be able to use this in future DWC or
    recirculating hydroponics experiments.

    I think it would be very useful in small hydroponics, aquaponics or
    aquarium applications for water oxygenation.

  14. This is not fair that they have done this to your clip Dale…..
    This is your original clip & would be helpful to many & you deserve the
    credit for your build/clip…
    Is there any way we can help out ?

    might try on of these. Thanks. I would give this a H20’d Thumbs up :)

  18. venturi’s are not efficient at all at aerating the water, as in order to
    have an effect, you need pressure from your pump, which means you decrease
    pumped water volume

  19. what would happen if you pumped more air in the air line with a air pump I
    think im going to try that

  20. Awesome venturi, the small bubbles look excellent o2. If I add a venturi
    tube to the down pipe of my bell siphon it should create the same effect?
