    There was no aspect of the sensor control that needed setting up by the user, and yet all was adjustable.
    Plus every component of the drum was `(and is) available for instant shipping within the UK should any fault develop. I therefore chose the Aqua over the Profi as it fitted my needs best.

    Price didn’t come into it- I actually didn’t look at the price tags until I had chosen the product that met my needs. My partner had promised he would buy the drum filter in any case as a Christmas present that year, so it was a non-issue (he didn’t also buy the Bakki shower and Flow Friend pump unfortunately haha)
    indeed quality of components is what matters,
    i use parvalux 24v geared motors , no chinese cheap crap.
    i noticed alot of the cheaper end drum brands have stocks online of gearbox parts an other parts , makes me think they aint reliable.

    my motor powered my last drum , and now installed in my new drum been working for 18 months totally faultless.

    The bypass bungs in my drum are actually not UV stable- they become brittle and crack after around 18 months use. Iím currently on my 3rd set of 4 of them. Next time I change them Iím going to glue a disc of thick pond liner onto the UV side surface of them to hopefully protect them for longer. It does go to show though how much damage a submersible UV can do to some items. You definitely wouldnít want it being able to damage the actual sides of the filter.
    I have seen lots of posts that suggests that the oase drums are not uv stable but seen no real evidence?

    They are not constructed from abs plastic they are made from GRP duroplast that is some kind of glass reinforced plastic (what plastic I donít know) but it seems to suggest that grp is highly resistant to uv.

    I would really like to get to the bottom of why a uv cannot be added.

    Interesting, I have searched around and I have seen nothing to confirm this.

    Iím not sure on the difference between uv stable and uv resistance. I am also not aware what the implications would be if they are not uv stable and a uv was added.

    They are made to be outside in the elements Profidrums, combi drums etc

    I've wondered this too. May be more to do with other components within the drum that would break down under constant uv. Warranty nightmare for them? Nexus is supposedly the same as I was looking to put a uv in the intake side at one point. Believe others have done it with no issue Profidrums, combi drums etc and isn't there an all-in-one Easy pod with UV? In the end I chickened out and went Oase + Gravity Bitron. I'm such a woose Profidrums, combi drums etc

    may give off chemicals , us as hobbyists wouldnt notice until fish become sick if that happens, they may not show signs though it could effect breeding , and other long term problems that we may not be aware of.

    would be worth asking them why UV'S aint suitable.

    I had the convo once with an Oase distributor whilst having beans on toast around the lunch table at cuttlebrook

    I can tell you what happens to non UV stable plastics though- they go brittle and split. This is what the bypass bungs do in my drum. They are fairly thin and cheap, look a bit like Pringle tube lids tbh, so I really don’t mind replacing them every 18m. But you would really not want this to happen to any crucial parts of your filter such as the walls!
