    Where to install Amalgam UV

    Just installing a Filtreau HF30 i was planning on fitting an Amalgam UV into the drum but looking at it, i don't think there is enough room under the drum to get the UV under it without it fouling on the drum , plus drilling the side of the drum box would take me very close to the bottom seal and i'm worried it may end in disaster, My dilemma now, is where do i install the UV ?, my setup is 1 feed runs bottom drain to drum second feed is skimmer line to drum after the drum it goes through the pump then to bead filter then return to pond, just not sure where to install the UV.

    Installed mine today.

    I refused to drill a hole in an expensive filter so I ordered mine with 2 extra outputs, the 2 outputs to the outside have plenty of clearance for a UV. This is on a Synergy 55, not sure what the drum you have is like.

    I then got a 4 inch rubber straight connector, chopped about an inch off then got a 110m drain pipe cap and chopped a little bit off. After this I drilled the hole for the tank connector in the end cap fitted it all together .


    This worked, however I'm not happy with it as it's wasting to much of the bulb.

    My plan now is to get some 3 inch pipe with a 4inch to 3 inch reducer so I can actually slide the bulb in further and not waste any of the uv.

    If you put a T fitting into the drum it will then allow you to fit the Uv down into the pipe.
    if it was me I would probably put it on the skimmer side rather than the bottom drain.

    Hi thanks for the reply, your idea of a T fitting has given me an idea, i could add one i was thinking of replacing one of my bends on my return pipework with a 4" T fitting, then capping off the top of the fitting and cutting a hole in the cap to take the tank connector and dropping in the UV so it will be sitting inside my 4" return pipework with clean water passing over it between the drum and pump, maybe this would work.

    the hf 30 leaves very little room..... i have syn 35 as well and theres much more space, i put a 1 1/2 inch tank connector in my hf30 to feed spray pump , but i dont think you can manage an amalgam in there

    After breaking my amalgam in the drum I have bought a 4” oase UV to connect out of the bio chamber.
    decided this was the best option for me.

    Hi Phil,
    I saw this on eBay as an idea where the amalgam may fit on a hf30.

    Cheers

    Manged to cobble something together today and fit Amalgam UV in my pipework after the drum, swapped out a 4" flexible rubber 90 bend for a 3 way flexible 4" T fitting then capped off the top of the T fitting with a plastic cap, then drilled hole in the plastic cap, fitted UV through the cap with a tank connector so Amalgam in now sitting inside the flexible fitting with all the clean water from the drum passing over it, I think i will swap out the rubber fitting for a pressure fitting though in case the UV has a detrimental effect on it, picture seems to have come out sideways for some reason 20200703_180124 (1).jpg

    Another thing with it being placed there you can't accidentally see it which is definitely safer for your eyes

    Looks good, tidy job.
    hopefully the UV doesn’t effect the rubber boots.
