    Any Opinions / Experience on this Protein Extractor / Foam Fractionator?

    My attempts to create a home made foam fractionator that is discreet/invisible and works, have failed.

    I also need a filtration solution to my skimmer line.

    Current train of thought is to run a small bead filter off the skimmer line, and from that into a protein extractor that is discreet and also gravity fed back to the pond.

    Had my eye on this since middle of summer, when it was priced at £149.99. I like it because it can be reasonably well hidden amongst the rockery plants behind the pond.

    Finally got the money together to buy it, and its gone up £80 to £230 which seems a lot of money for what is essentially a plastic bowl with a venturi. Not sure at this stage if I could bring myself to fork out that amount.

    It is not something I've ever seen up and running on a pond so I wonder what other people's thoughts are or if anyone has experience of using one:











    There is currently a second hand one on eBay but it just looks like a pile of junk with bits missing, and the guy who isn't a pond owner wants £200 for it as he's seen the current price of them new. I'm not sure I'd even offer £50 for it in view of the missing bits.

    it looks a bit small?
    i can't really see how that will remove much foam?
    to separate foam i think you generally need a large area of water/air agitation to separate it.

    i'd thought about tryijng to add one to my showers gravity return, but don't seem to get that much foam?

    or trailling my old Deltec AP851 protein skimmer on my pond next summer, as i modded it on my old reef tank to take about 2-3,000 lph throughput.

    Flows at circa 4500 lph and 60cm diameter with 2" outlet.

    I suspect it is bigger than it looks.


    Never had any issues with foam in the last pond, but this new one is terrible, even now in winter there's bubbles on the surface despite having no above water inlets. So definitely need a solution of some sort.

    Can never tell if something will work till you try it I guess, but its a lot of money just to see, and as with most Koi related manufacturers, if it doesn't work they'll simply say I'm using it wrong!

    no help to you what so ever. but i only ever had foam problem when i restarted feeding in spring with wheatgerm .so this year cut back on the amount on each feed and no foam. i read that foam is caused by koi not digesting all the protein in there food. and as coppens wheatgerm has 40% protien . might try medikoi wheatgerm garlic belive it has 20% protein.

    I had something very similar on a previous pond and it was quite good tbh, produced a constant effect rather than the noon
    or bust of sone other skimmers

    They are getting exactly the same food as previous years, albeit more because they're bigger now.

    Like yourself I have always understood the cause being protein from undigested food. But the point you made about cutting back on each feed is interesting - Did you still feed the same amount overall but spread over more feeds, or did you reduce the amount altogether?

    The Dutch fella off Koi TV says foam is caused by bacteria dying off when there are big gaps between feeds. He said the reason you see much more foam in the mornings is due to bacteria die-off because you haven't fed since the evening before.

    He reckons if you spread feeds out evenly over each 24 hour period, still feeding the same amount in total but split every 2 hours day and night etc, the foam problem will go away.

    Hard to swallow that idea, but if it matches with your experience maybe there's truth in it.

    i used to feed before work then again after work and it was chuck it in and off to work. since retiring put an auto feeder on and feed 3 times a day but not much and hand feed a little as well that's from spring till end of July. we then go four times a day feeding a little more plus treats of sugar puffs,calci worms and bread spread through out the day .
    so yes without knowing i go the same way as the Dutchman.
    Also the foam problem was always worse first thing in the morning clearing up by about 11am. first feed was 06:30 and second anything thing from 18:30 onwards. they have also grown quicker with the regime.
