    Filtration ideas for economy

    Hi All,

    I used to be an active member on here 10 years ago but have just been enjoying my pond in the meantime and without too many issues (Davej) used to live round the corner to me.

    Anyway, I'm looking to change my filtration to something that's more economical to run. My electricity bill like most people is starting to get a bit excessive. Sadly I'm at the point where I need to either get my running costs down a lot or close the pond down.

    I currently run a sieve to bead with a 250w badu pump pushing the water through the bead. My pond is approx 3400 gallons and I've been turning over about 2200 gallons an hour. I have low stock (only 8 koi but reasonable sizes). I'm gravity fed through a bottom drain.

    I was thinking I could probably change to something like a Nexus 220 with a more econimical pump like a superfish but as I've not really followed the latest invovations for a while I would like some feedback or ideas if this is still a reasonable path or there are other options I should consider. I can't really spend too much..so a drum is out of the question...although I do have an unused bakki shower in the shed

    Appreciate any advice

    Paul

    bakki showers don't lend themselves to cheap pump costs, i know...
    but you could change your pump to a more modern adjustable and economical vario type (aqua forte, evolution aqua, jebao ect...)

    the most economical set ups these days run air lift pumps, but generally require a lot of installation work.

    another solution that is popular on the continent is a variable high flow, low pressure propellor pump,
    they are designed for low lift short travel, but use a lot less watts per litre pumped.
    i have seen them used in the last chamber empty chamber of a multi bay, pumped straight out the side and short 110mm run of pipe to the pond.

    Thanks. They look good but looks like you need a setup where it can be submerged. I used to have a bay filter years ago and didn't like the maintenance

    Any of the pumps mentioned any good with my existing setup? I was thinking I probably need to move away from a bead filter to use a low wattage pump.

    One or two people of the forum were desiging airlifts last time I was on here but like you say that would be a lot of work that my wife wouldn't permit

    Here's my sushi-bongs (airlifts).

    The entire pond is designed to run off a 58W HiBlow XP80 with the air output split between the aerating bottom drain, and two 110mm wide airlifts (theoretical 36,000lph from both). No water pump except if I have the (yet to be installed) water blade running. The design of the airlifts also acts like a protein skimmer.

    Additionally the chamber used for the airlifts is actually destined to hold anoxic filter baskets. This means the pond wont need the water consumption for trickle feed to dilute Nitrate because the filter converts to Nitrogen gas without going through the entire Nitrogen cycle.

    Bottom drain 110mm, Skimmer 110mm -> drum - 110mm -> bio (temporarily) -> 2x 110mm returns -> anoxic chamber -airlift-> pond.


    You could do a U bend style lift - so it's just pipe. Simply use a post hole digger to make a hole deep enough for the lift and you're sorted. (you'll need air bit that's part of your design).

    Eco Pond 2.0: 13,000 litres, 58W airlifts, 1300l anoxic, Solum 16. No pump.

    i'd have kept the multibay they are ideal filters now, with a good drum in front of it...

    if you want easy maintenance you can't go far wrong with a drum,
    you don't need a fancy bio chamber after a drum as all of the crap has already been taken out.
    but JBR do some decent sized units for a reasonable price.

    you could do a QK25 or filteau drum with a 1000 litre IBC for bio. that's plenty big enough.
    as i don't think the average combi has enough space for bio especially the 20-30,000 LPH units with 100 litre K1 chambers.

    If I get my way and funds allow that is exactly what I want to do drum and 1000lt tank . Get shot the multibay

    Thanks guys! Food for thought... down the rabbit hole I go

    Any recomendations on a good cheap drum? they were a bit expensive last time I was looking

    do you have any drawings or designs of this? It might be too difficult as my filter bay is brick built with a 6 inch base slab.

    man option is it make the same as mine but the bottom has a U bend back up. There’s a thread on making airlifts - https://www.koiforum.uk/pond-construction-pond-build-diaries/25586-airlifts-pumping-water-gravity-system-using.html

    I'd also suggest going for Drum - Anoxic - air lift pump as being the ultimate in low energy consumption koi filter set up.

    The drum will only use about 11watts when it's not washing and a 40 watt air pump would probably be enough to power a single 110mm air lift. So 51 watts in total, or if you want to have more air have another small air pump to add air in the pond if you wanted.

    In my set up I have drum - moving bed, - DIY shower filter (that pours back into the bio chamber) - air lift pump return to the pond.

    So my energy consumption is:

    - 11 watts for drum when not washing,
    - 58 watts for an air pump - this supplies air to a moving bed chamber with 210l of k1 in it and also the air lift.
    - 28 watts for a conventional pond pump (a 10k vari) on its lowest setting for the shower/trickle filter uses.

    So just under 100 watts all in.

    It's probably stating the obvious, but realistically, if you want a low energy set up, then shower filters and any high pressure filters (beads, sand etc) are best avoided.

    Would you have any pics of your air lift Mr T.

    Hi John, if you click on the link Nick posted above and scroll up to posts 3 - 5 on the thread, there's a few photos of my set up there. Filtration ideas for economy

    Hi Paul,
    Are you happy with the performance of your sieve? If you are, then there’s really no reason to swap it out for a drum.
    In your case the thing using the power is the bead- so what you need is to swap your bio to something more efficient, your mechanical can remain as a sieve if you’re happy with it.
    ‘You could add a moving bed of dancing plastic for your bio, without the back pressure of a bead you can get away with a much more efficient pump for the same flow rates. It’s just a matter of how much space you have really, and it’s possible to DIY this using any large container and a few mods if you wanted to.

    Alternatively could you not just deploy your shower after the sieve? The head height will reduce flow rates for the same wattage, but there are lots of very economic variable flow water pumps on the market now with a lower power consumption than what you have now.
