    Is it just me, or isn't a drum not just really dumb?

    I've been looking at drums because everyone raves about them trapping fines and self cleaning and constituting a trickle in water change when it cleans.
    My initial concern was how much water would that use, then I thought:
    If you are trapping the fine particulates in a mesh and then washing them out to waiste, why trap them in the first place? Just trickle in and the trickle out to waiste will contain the fine particles anyway.
    Or am I missing Something?

    ... The title is slightly tongue-in-cheek, but it did rhyme!

    You would need more water without the drum, when the drum is washing the waste has way higher concentration of dirt than the normal pond water so without the filter the trickle rate would need to be ridiculous

    Thanks for clearing that up Kevin.
    How much water does a drum use then? I've read that they clean out every 40mins!

    I don't have a drum filter myself so can't say exactly, but I think it would depend on messy size and amount of solids in the water. I also heard that it starts cleaning more often over time as a biofilm form on the mesh, though it can probably be cleaned with a power washer

    I have run a queni drum now for two years and the crap it takes out is awesome, no trickle in or out would ever take out that amount because the drum is pick the water up from the bottom drain where all the much fall. I trickle in and out is at water level so would never work the same

    Hi

    I think you may be missing something

    A well designed drum filter will not really act as a trickle in to the pond as the majority of water sprayed on to the screens will go through the screen and down the waste shute. It is only where you have a poorly designed drum with an inadequately sized waste chute or insufficient pressure on the spraybars that you tend to add anything to the pond.

    The drum will be taking water heavy in waste that has settled on the bottom of the pond whereas as overflow will be of water at the surface of the pond that should mainly be particle free.

    There are 2 different potential systems drums can have to feed the spray bar- mains fed (which may be pumped) or pumped from the drum clean side. There are pros and cons to both of these systems. The latter does use some pond water so needs replacing.

    When the fish are feeding heavily drums with sensors will clean more often- mine will clean every 20 mins in summer but more like 40 mins in winter. It uses around 1.5 litres of water each time. I make sure my trickle in is always running at more than 5 lph to make up for this. In reality my trickle in needs to run higher than this to change a decent amount of water per week anyway. 30 lph would give me a 20% weekly water change.

    This could be the right place.....

    I have my new Oase Proficlear Drum filter set up in a temporary position on the patio and the water clarity is the best I have seen in twenty years of pond keeping. I'm staggered.....but I am a bit confused by the manual in terms of cleaning intervals.

    I have a large bucket hooked up to the waste to collect the dirty water and I'm amazed how dirty the water has been. Eventually when I've built the new filter shed all the waste will be pumped into large water butts for my wife to water her plants, so little will go to waste.

    Here's a question for you regarding the manual.



    Why would you buy a drum filter if you had a pond with no fish.....

    I've tried to get my head round the interval timer, which appears to be in addition to automatic timing, rather than instead of.....

    As we keep filling the bucket, I've now set the interval timing to zero to see if it reduces the number of cleaning cycles. No problem either way as I'm so chuffed with the water clarity, but I'd rather switch off cleaning cycles that weren't required.

    Am I missing something?

    How do I stop the Photobucket watermark from appearing? Is that because I'm using the free option or is it part of the settings?

    Hi. My profi drum uses one UK litre for every washing cycle and it cleans between 24 and 48 times a day so max 48 litres per day. Nothing really. I lose more to waste via my 24/7 trickle.
