    Well it is up and running made a few alterations so now just need to see if it will foam.

    It's quite noisy so may need to alter the pipe coming out of the horizontal pipe?

    Got a few photos of the various attempts so will add them later when I am on the laptop.

    Made a couple of alterations to the air lift this morning and took a few photos. No power at home at the moment or I'd put the photos on here.

    Power's finally back on so will see if I can add the photos now.

    Unfortunately the photos are all showing up on their side for some reason

    This was the first attempt using a drive tube length of 1m just to see if it would work.

    2018-06-07 18.18.56.jpg

    Second attempt with drive tube cut down a bit.

    2018-06-07 18.27.03.jpg

    Third attempt with drive tube cut down a bit more plus I added an end cap onto the top of the drive tube and altered the pipe work where hopefully any foam that is produced will come out. Just for the purpose of testing and proving the outlet was set up to empty back into the pond just in case it fired out water. At least the photo's the right way up this time - must only allow photos in landscape orientation not portrait

    2018-06-07 18.58.58.jpg

    Fourth attempt just altered the foam outlet.

    2018-06-07 19.23.25.jpg

    This is how the fourth attempt was set up. The inlet at the bottom was a 2" pipe with a pump cage on the end to stop any fish getting pulled into it.

    2018-06-08 12.30.58.jpg

    Fifth attempt. Replaced the 2" inlet at the bottom and fitted a 4" pump cage to hopefully aid the flow into the air lift. Also the T on the horizontal pipe has been removed and an elbow has been fitted to the top of the drive tube. In the first attempt the pipe was 1030mm long between the top and bottom Ts.

    2018-06-08 12.40.01.jpg

    Fifth attempt in situ.

    2018-06-08 12.48.01.jpg

    BTW the photos really shorten the pond size as it looks like a builder's bucket in a couple of them

    I'm going to have another go at a longer drive tube now I have got the 4" pump cage on the inlet just to see what happens but even with the first couple of attempts it shows it is possible to have the water coming out quite a distance above the water surface even with a badly designed air lift. I did try to stick to Trace's original design but it's always worth having a tinker here and there to see what can be achieved and glad I went for flexi rubber boots and 2" pipe. Was just lucky with a few additional fittings that made the pump cage additions possible.

    The air stone is a modified 30mm x 130mm using 8mm air line fed from a 60 lph air pump (I think it's a 60 will check that later). At least I didn't knacker the air stone this time !!!

    The air line is probably about 4m long so that could be shortened in the final version but as I said earlier it was just a trial and error project to see if it would - work at all, give a steady flow, give a decent flow and also if it could lift any height above pond water level. So far I think it has done all of those not at the same time but maybe the next attempt will, hopefully.

    With the double elbows it was quite noisy and currently it's not producing any foam although the movement across the surface of the pond has cleared 90% of the foam you can see in the first 2 or 3 photos.

    It's difficult to see the flow rate on the third, fourth and fifth versions as the outlet pipe is closer to the water and the angle the photos are taken don't help either.

    Thanks, and not a trebuchet in sight.

    I'm going to try with a longer drive tube again now that I've got the 4" cage on the input just to prove a point or not as the case may be


    When it is running there is quite a lot of vibration on the air lift and with the alteration to the foam outlet it is definitely a bit quieter. Just can't work out with all the foam on the surface of the pond there is none coming out of the air lift. Is this because the DOC is more dense in the foam on the surface and not so much at the bottom of the pond?

    Thanks Fred, I was well surprised when the water came out of the outlet in the first attempt which was probably at least 12" above the pond surface

    Just checked and the air pump is a 65lph

    Surely it can't be that difficult as at the end of the day it's just some pipe some Ts, an air stone, air line, air pump and water isn't it.

    Attachment 23724Attachment 23725

    A couple of very rough ideas of what I'm thinking of trying.

    Just need to get all the parts together and give it a go.

    Got the pipe, Ts, stop ends and couplers this afternoon just waiting on the air pump etc which should hopefully be turning up on Friday.

    To start with I think I'll try to have it mounted in the pond and hopefully if it works and I can get it to lift more than a few inches from the water level I may have it feeding a DIY two barrel filter system. If I can only get it to lift a few inches - steady on now I am the wrong side of 40 and age makes fools of us all sometimes then it may have to be mounted outside of the pond to add to the length of the drive pipe?

    Just gone for 40mm pipe with push fit fittings so I can adapt as required and maybe go solvent weld or compression fittings once it's working properly.

    Question is will it be like a geyser or an old gezzer ???
    Got it now Cheers.

    The 40 mm waste pipe is a bit more flexible than pressure pipe so it should be easy to put a slight downward slope.

    I thought the elbow on the top of the drive pipe allows the foam to be piped to waste or would it be better to have the foam coming out of T No. 4?

    Was thinking of extending the pipe out of the top of T No. 3 by the length of a coupler.

    Anyway as I have got push fit I can try it with or without the extra bit of pipe on top of T No. 3 and with and without an end cap.

    I already had a small amount of 40 mm waste pipe which I can use for the short sections between the Ts and elbows etc. then save the full length for the drive pipe and horizontal pipe.
    Mark the depth of the joint into the fitting then 2/3"s below it apply a gentle heat all round pipe with a Blow lamp and slowly ease a slight bend into the pipe warm an area around 4"s long or longer or easier still glue an offset bend into the fitting, that'll give you a 45 degree angle though which maybe a to much?

    It's really that simple Tom. For a practice you could make one out of 1.5" or 2" waste pipe and flexi rubber boot fittings.
