    Does anyone know if its possible to create a DIY diatom filter? I've looked around and I can't find much on google. (I'll do more searching now).

    I don't see why creating a filter should be hard... I think you would 'just' need the diatomaceous earth and a very fine sieve to hold it. Then force water through the sieve. Surely that is all there is to it?

    I have no idea where to get the sieve from though... Hardly anyone seems to know what diatom filters are.... The few pool shops that do only haver large filters and no sieves.


    Any ideas?


    Thanks

    Have you tried any of the water purifying shops? The equipment used, might have a very fine sieve\mesh that you could possibly use\modify. Other than that, I am just as clueless as you... :)

    No? As in no to the felt? (I'm sure that normal felt wont work. Perhaps they were talking about something else). Or no to the DIY diatom filter idea as a whole?

    Can I get the slightly longer version? :)

    Thanks

    No to the filter as whole - it works under some serious presures as well as very specific fine filter media.

    Years ago I had a Vortex diatom filter. A glass jar fitted on top with a powerful pump. I cannot remember the internal construction but it looked like a canvas type bag ( bank bag ?? ) to keep the diatomaceous earth from being pumped into the fish tank.

    Just looked at a TFH magazine and there is Vortex advert address www.diatomfilter.com

    Priced at US $120.00 with 3000 rpm motor shaft connected directly to impeller.

    Thanks Henk,

    That is a good point... The only DIY ones I've seen is people using micron filters and charging them with diatomaceous earth. I doubt it works as well as the proper diatom filters but it still might be worth trying.


    Anyway I got a really good deal on a UV filter. So I don't need the diatom filter so desperately any more. Still if anyone does figure it out I'd love to hear about it.
