    Hi guys and gals,

    So my canister was running fast and slow from the out exit, so I decided to open it up and clean it but the rod that sits in the propeller and motor broke while removing it, I made a mistake by glueing it to the propeller and now it's not spinning, any idea what can be done or where I can get the pin and propeller?

    What did you glue it with? Some glues can be broken down, and if so you can undo the problem of it sticking. Then you can glue the shaft together and let it cure properly next time, before re-inserting it.

    However, this isn't a guaranteed fix. That part won't be stable and due to the heat generated and constant use, is liable to come apart again. So my advice it to try and bypass the current problem you have, get as much use as possible as you can while you save up and look for a replacement filter.

    One small hope you have for replacement parts, if you still want to attempt that route, is that many "brands" are simply rebranded Resun models. I'm not too familiar with which models correspond to which brands, but worth looking into if you're determined to keep this filter.

    Great info. I am sure one of the LFS could get more info on this.

    Ok thanks, yes some cheap glue used to see if the problem was solved, can I just leave it in water to come apart or is there some chemical that won't cause any harm to the propeller that can be used?

    I know some of the stores that specialise in aquariums carry a bunch of impellers - so if you take yours to the store they will match one to yours...

    Most likely a different brand as @SalmonAfrica as many brands have interchangeable parts...

    I don't know much about glue but I have an alternative "thinking outside the box" idea that I used on my canister when I was waiting for a new impeller to be shipped to me. I didn't want to potentially loose the BB in my canister so I bought a relatively cheap internal power filter and connected it to the inlet pipe to pump the water through the canister, it also acted like a pre-filter which is a plus in my opinion. It worked amazingly well for the 10 days I waited.

    Ok cool thanks, I managed to get the pin off the impeller, so do I need to change impeller as well or just get the pin?

    Pin and impeller come as one unit I think so you'll have to get both

    Just purchase a cheap power head or fountain pump available at most big hardware stores and strip the impeller. I have even seen them selling the impellers separately you may even find one with the correct size magnet to fit. I have done this several times to save expensive out of date filters that needed new impellers. I have even cut impeller wings shorter to make them fit. (Did this on an expensive Enheim once, since I was not prepared to pay the extortion price for the new Enheim "original" part. Worked 100% to date)

    I agree with @Slade in this hobby you need to think out of the box, especially in South Africa, since almost everything for our hobby is imported and by the way @Slade , thats a brilliant idea!!

    You could try a similar size plastic lollipop stick and cut to size

    Stainless steel welding rod to the same length works as well.

    Thanks guys but I am about to throw this Canister off my balcony, managed to make a shaft, but now it's leaking, bought a new seal slightly thicker, still leaks, does the head also needs to be opened up and cleaned, been struggling with this the whole long weekend, will blockage cause a back pressure into the canister for it to leak?

    For leaks you need to examine a few angles. Back pressure can cause leakage (although sometimes the pipe connections will give out first), the seal can be the problem (must sit flush with no twisting), the clips must click in properly without having to force them down, and in fact when putting the canister head back onto the body, it should be easy without you having to force it. Once it is attached and clipped on, be sure that the head is level. Even a slight tilt between the head and the body causes canister filter malfunction.

    Other leak issues, I've found, come from improper connections between the pipes and the heads. Anything from old pipes going hard and cracking, to not getting a proper seal on the end (different models have different ways of ensuring this - either a clip, or a screw-on type system). With the screw-on types, the threads need to line up properly. Often you'll still be able to screw it on all the way, but you'll see it's skew, which is an improper seal and allows for leakage.
