    New Draco drum newbie

    My new RDF has been running for a week now and as the days have gone on the cleaning cycles have increased to less than 5 minutes, my filter is a four bay with a drop in Draco, itís a stepped water exchange ie the first bay fills the second and the second fills the third, if I move the float switch down below the surface the time that it takes to clean the end bay will be drained. ??? I think this is the way this particular set up will work. My pressure from my tap is ok 2.5 bar and get a mist when cleaning. Is this acceptable for a new RDF to clean this much... thanks in advance

    So the Draco has been gravity fed or pump fed? I'm assuming gravity?

    I found that a drum installed on an existing pond goes through phases - first it takes out the immediate matter, then as the fish rummage around it takes out progressively more of waste in the pond until it finally slopes off - except when summer comes around and the drum starts pulling out additional algae. Is the pond in the sun?

    What's the size of pond and flow rate you're normally using?

    Is it just the bottom drain or is there a skimmer feeding the drum too?

    Can you get a container under the waste chute and collect whatever comes out during one wash cycle. If there’s waste present, then the drum is working fine, but if it’s almost clear, then you may have another issue.
    Can you see the water level on the dirty side of the drum, to confirm there’s no restriction between bottom drain and drum?

    Iíll try the wast chute with a bucket tomorrow, itís brand new set up 4Ēbottom drain and pipe work with 4Ēpurge valve, been purged twice now in two weeks, 58 micron screen maybe getting clogged to quickly. The pond is a liner construction the old algey is being sucked through the drain at a rate of nots. The purge works absolutely fine no air locks, Iíll purge again tomorrow. Thanks for reply

    8,000lph - you would be able to get that through most Draco (most models seem to be at least 16,000lph except the Draco2).

    Which Draco is it btw? Draco2/Origin etc.

    One other thing, compare the difference in water level on the outside of the waste chute between the level before and after a wash cycle. For me, it’s optimally 5cm, when this gets down to 2cm, I know it’s time to jetwash the screen. At peak, this is once a month, but then my water pressure is not that good. It shouldn't be an issue with a new drum, but you never know what is on the screen. A quick pressure wash won’t do any harm, see how it affect your wash interval.

    Should be 11,000lph+ depending on the model, so should be fine with 8,000lph

    it will go off a lot if its the 1st time you had a drum on the pond, i had mine running for a week before i put fish in there and it was the same, after its done a clean get your phone and do a video of the inside of the drum on either side of the spray bar and you will see how much its getting off. it will slow down after a week or so id imagine

    Interesting on the frequency thing as I’ve had mine a few weeks and it varies between 25mins - 90mins depending on time of day.

    However I’ve had to net a couple of fish today and noticed that it’s been cleaning about every 9mins! I think the activity of the net being in the water that has made the fish very active has stirred up some waste. So I gave the sides a brush and cannot believe how much debris it freed up - it been flushing about once a minute to clean it up. think I’m going to start doing a sidewall brush once or twice a week for a month to see the impact.

    Brush down - giving the pond bottom/walls a brush with a pool brush. Not the best idea with a liner as it can make holes in it as it gets older but for fibreglass'n'flowcoat it's fine.

    Also have a look for string algae - if that builds up and isn't removed it can cause problems. Not noticed a problem myself with coping with it.

    I doubt you need one - best to find the issues. Do you have photos?

    Is the 10000 vario the only pump you have on a 12000 gallon pond?


    If so, running at 80% estimating 8000lph, this would give you a pond turnover of about 6 hours 45 mins, which is well under the recommended.

    Hi Stephen. Looking at your photos the float switch is quite high (well compared to how mine is set up at least).

    If you find it's cleaning too frequently, on a gravity set up try undoing the clamping bolt and dropping the float switch a small amount and see if that reduces the frequency of washes. That might be enough to sort it.
