    Filtration on a budget

    Hi everyone,

    I am starting a build and could do with some advice.
    I have posted in the build Forum, but I thought I would seek specific filtration answers here.

    My pond is going to be formal and 3000 x 2000 x 1500 deep, giving me 9000 litres total. I am planning on an aerated BD and a wall skimmer. The pond will be mainly built of sleepers and a liner.

    I will be stocking with Koi only and will keep stock levels to a minimum, perhaps 8 fish maximum.

    I already have an Eazypod with UVC onboard and will be using it gravity fed, but I now realise this won't hack the volume, so I am going to need more filtration.

    For the BD I am considering putting a Vortex pre the Eazypod and then a DIY moving bed media filter post the Eazypod and then into the pond. I watched a few videos of construction of the moving bed and it doesn't look either expensive or particularly difficult to achieve. I was considering buying a secondhand 4 Bay and converting it?

    Is this set up likely to manage my demands and where would I place the pump? After the Eazypod and before the media?

    I am not totally in the dark, but do not have experience of these things....

    I have looked for a definitive drawing or similar on line, but I must be searching for will o the wisp...

    Yes I have been reading a LOT, including this one. I like the 4 Bay idea. I might drop him a message.

    If I was you I’d sell the easypod, then buy a secondhand sieve filter, there’s one on eBay now for £200 but it now. Then I’d make my own tank for a moving bed filter.

    could do the whole lot for probably £200 on top of what you’ll sell the pod for.

    Pods are good for some things but I think your plan of vortex and easypod then into a moving bed is more work for less for more money.

    Many thanks,

    That makes sense. I have seen a Nexus for sale as well at £500 and wondering if that would be a one stop solution?

    Personally for me I’d rather the sieve and moving bed. Much better, cleaner, finer, easier to clean & cheaper.

    If your Eazy Pod has a built in UVC it can only be pump fed I think you'll find.

    Sorry to butt in! - just wondering why that is? surely, if the UV is "dangling down" into the incoming water inside the pod, what does it matter if the water is being pushed or pulled past it?

    Don’t worry about it and just sell it and don’t buy a nexus either Filtration on a budgetFiltration on a budget

    A nexus may not be brilliant on it's own for fines, but it is still a big step up from the easypod in my opinion for the size of pond mentioned, a drop in drum could always be added later if funds permit

    Hi guys, thanks for all the responses.

    I might be dropping the size down a touch as the ground is proving "challenging", which is as expected. I still haven't cleared everything as some of the roots are being a pain to dig out.

    The size might now be 1.5w x 3l x 1.5d, giving me 6750 litres.

    The sieve and Bio method does strongly appeal to me. How often will it need cleaning out roughly during peak conditions? As previously mentioned, I am hoping to keep stock levels as light as possible and will be stocking with 20cm fish initially. Probably no more than 8-10?

    I am in no rush at all, as I won't be looking at going live until Spring at the earliest.

    Thanks again

    My sieve is only on my skimmer line (Drum on bottom drains) and I have to clean the mesh on mine every 2 days or it starves my Nexus of water which in turn feeds my blade/low return
