    For those thinking about it: a test - pump fed pressure filter vs Drum filter

    As part of the initial test of the drum as part of the new pond, I ran the pond return from the Bioforce Revolution 9000 through the input of a DracoDrum Solum16 to see what the results were - I was rather gobsmacked.

    Old pond is about 1700l and the revolution has been cleaned out recently as part of the new year regime. Normally 6000l/h pump in the lowest point of the pond pushes through the revolution then back to the pond via a veggie filter/waterfall.

    In this test the water runs through a white tube into the input side of the solum. the inlets are blocked off by plastic bags with clips.

    I left the setup running, fresh from an initial clean (the wash water pressure is low by the tap cracked open). I watched over about 25 minutes as the input water slowly rose up and then triggered the sensor, this was the result:

    So I can now safely say I'm a drum convert. The mrs didn't believe me until she saw it.

    Ha ha, I did exactly the same thing, and photographed the results which are identical to yours:

    It's amazing the difference of having a drum. With the bottom drain. Best thing invented for a pond

    Ahh - tuning tips

    So when you start - the sensor is high so that you get the maximum amount of poop out per wash. The down side is that the dirty water pressure on the mesh may force some fines through.

    Once it gets to 99 minutes between washes the screen shows an odd character so you know.
    At this point drop the sensor down so it washes every 15 minutes and the dirty water pressure against the mesh is far less so you start filtering fines.

    A further couple of observations:

    First - as the sun causes algae filaments to grow, the filter removes it before it has chance to grow further.
    Second - stones, be careful if your pump picks up a stone, a simple large mesh in the drum tank helps prevent any stones appearing in the drum and possibly tearing the mesh or the rotary seals.
