    Hi Martyn,

    I'm presuming you'll be using the ibc as a moving bed (bio) filter?

    If so, you'll need some form of mechanical filtration in front of it - whether that's a drum, sieve or a static bed filter. You really need to remove most of the solids from the water before your bio filter, so that the bio filter can do what its intended to do i.e. to remove ammonia and nitrite from the pond water.

    If you don't have any mechanical filter before your IBC, all that will happen is the Ibc will get full of crud and any crud that is held in suspension will just get pumped straight back into your pond, but will get chopped up into even smaller pieces by your pump.

    I really wouldn't use grog as a mechanical filter. It will very quickly be a breeding ground for bacteria and parasites and be a pain to clean.

    I'd say a vortex (with brushes added as an option) would be better than a vat of alfagrog.

    But if you don't want to freeze your hands off in winter having to keep cleaning brushes, I'd say a second hand sieve would be a better option than a vortex.

    The aim for effective mechanical filtration is it removes solid waste from your water as quickly as possible. All grog will do is keep it in the water, but hidden from view and add to the effort needed to then remove it.

    ok so alfagrog will hold waste what about splitting the first ibc down the middle with egg crate partitioned one side jap mat and brushes on the other side then connected to second ibc moving bed that will be pumped back through inlet pipes ? im new to the koi world so my pond build is a diy build thats on my youtube channel and im at the stage of finishing the block work and ive just acquired 2 ibc tanks for free have only been a koi keeper for the last five months my channel is martyns koi pond and garden just a little bit more KOI POND BUILD - YouTube as i said im a novice but like to diy build purely for pleasure and saving money alb martyn

    It's gunna seem like we are picking holes in every thing you coming up with but we anrt at all just most of us have been there and made the mistakes so.others don't have to . .


    Brushes do a good job and have done for years people stopped using them because of freezing hands when cleaning them in winter

    Matting is good stuff but i think it's better for bio than mechanical as its a complete bugger to clean as all the crap gets caught right inside where you can't get to clean

    . Imo I would use a couple choices

    1)Smaller vortex with brushes
    2)easy pod
    3)sieve
    4) drum

    A lad on here picked up a second hand drum for 350 notes so there is bargains to be found . Or Personally a sieve cheap or diy

    That'd work better - as the media is way easier to remove and clean, although will still be a hassle.

    You'll also need to find a way to remove the muck settled in the bottom of the Ibc. Not sure how easy that'll be?

    It's probably best if anyone who has a Multibay filter (Ajm?) Can tell you how effective they are, as they work in a similar manner to what you are proposing.

    .... He beat me to it. I can only second what he is saying.

    Although I get why you want to use your IBC for mechanical. The truth of the matter is that you are making a big compromise in doing so and will create a lot of cleaning commitments for yourself.

    Multibays work . End of they do work and can work well albeit labour intensive

    I have a 5 bay multibay
    At the moment I have a settlement bay then the water rises up thought a 800 mesh before going in to brushes , matting and finally k1 water is spot on and gin clear at the moment but have a big fish load going in pond in summer .

    In summer I have a couple plans that I'll be playing with

    1) stick a sieve in front of bay and run 1 static k1 bay and 4 moving k1 bays
    2)binning the bay and going sieve and icb moving bed
    3) keeping the settlement and mesh bays binning the brushes for a static bay and having the last 2 bays moving bed

    As for removing the crud from bottom just have a ss mesh in the bottom about 6 inch from floor and some airstones underneath

    With the k1 make sure mesh holes are no bigger than 6mm

    With the matting and brushes if that's your way the wholes could be a load bigger

    Yeah I agree with above.

    IBC tanks are very good value as bio reactors with dancing plastic media- huge volume and quite compact. You need to find a way of preventing media leaving tank via the outlet. You also need a valve at the bottom for dumping to waste sometimes, and this valve outlet also needs to be protected from media leaving through it.

    As a mechanical filter chamber tho an IBC is totally unsuitable. You need something much smaller that you can easily do maintenance on. Whatever you use to collect the solid waste has to be easily washable and the chamber itself cleanable and should be easy to separate off from the rest of the system when you are cleaning it and dumping its contents to waste. This is the chamber you will be cleaning more than once a week in summer. Whilst it’s possible to DIY a mechanical filter- as a general rule I would say not worth it. By the time you’ve perfected the design and bought all the pipe connectors and bits needed to make it, you could have bought a purpose designed second hand sieve, Eazy Pod or Nexus for the same money- plus you would then have something your could actually sell on if you got into koi and s]decided to upgrade to a drum in the future. DIY filters are rarely saleable.

    Hi Martyn

    Don't get me wrong, I'm not against DIY filters, I have a DIY shower filter on my pond for bio filtration which has grog in it and works great.

    The Ibc will work great as bio filter so you are sorted on that front. But bio filtration is the easy bit. All it is is something with a big surface area that is conducive to bacteria thriving in it.

    The hard part is filtering the solids out.

    Koi produce a huge amount of waste. Way way more than I first realised. And the main hurdle you'll have in keeping them is finding a system that gets all that crap out of the water without you spending 2 hours every weekend up to your elbows in freezing cold stinky water.

    I would really urge you to consider your options carefully, for mechanical, even second hand is fine. The list AJM gave (post #8) is a good list to consider.

    By the way, others on here have built DIY drums and sieves, so have a look using the search function if you want inspiration.

    The wealth of knowledge on here is unbelievable mate years and years of experience up and down the county with people who are always happy to help just keep asking the questions mate .

    It's the slower time of year for the forum as a lot of members follow other hobbies over winter but stick with it make its all very worth while for that 5 mins a year when uou can enjoy ya fish before jumping up and asking your self did that fish flash what's that doing lol haha
