    UP goes the Ph, ready for any future TA reduction

    I don't even currently have a high TA, but after getting it down I had to play around a little.

    This didn't turn out as impressive as I planned, but I also only used a bunch of spare stuff left laying around for the most part. It uses four venturi valves I paid $1.63 each for on E-bay but had to wait a long while for shipping from China to get them so cheap. I also needed a Polaris universal fitting only because it's where I intended to put it. It doesn't seem to seat well and makes an awful noise, but since I don't really need it right now I didn't bother with it.

    I think only two venturi valves would have maybe worked better, or at least make a more impressive cloud of bubbles

    Very nice.
    I built a modified venturi based off a design for this product
    Very easy to construct with some PVC board, glue and a couple drill bits
    This is a 3/4" test that would not work in a back-pressured setup but screams bubbles in front of a return jet. I have a scaled up 1.5" version that will raise pH in a hurry

    30k in ground vinyl lined pool surrounded by decking in the woods.

    If there is a way to do things less expensively and yield a superior product I am all ears
