    Hi everyone,

    Since loadshedding started again a few days ago, my Dophin C-1600 canister filter started giving problems. It is as if there is air inside the canister and it struggles to keep a steady flow, blows out lots of bubbles and makes a loud noise when struggling to get the air out. Can anyone give advice on how to solve this or what the problem could be? It is also leaking a bit of water where the top part of the canister goes onto the bottom..

    Thank you

    Firstly check if your seal is still in good condition, might just require to be re-seated. Then if air is trapped my C1600 has a button on top that one pushes to prime the pump. I generally battle with priming, I use pumping the button as well as closing / opening the outlet valve and stop / starting the filter to get rid of all the air.

    Thanks @Ren, I have tried everything now and it still doesn't work. Took the O-ring out and it seems quite stretched out so I'm not sure if that is causing the problems..

    Anyone have an idea where I could find a new O-ring? Do petshops stock it? I'm in Somerset West.

    Try.. While on, tilting until it's almost completely upside down, you may notice the bubbles.. It needs to burp that top button doesn't help much

    Best way to test is to open it up, remove all the trays and run it without any trays. This way you can confirm the opertion of the impeller. If the impeller is working correctly then it should pump with no issues and very little noise. A big canister like that has a lot of siphon suction and quite a big impeller, so it should pump water perfeclty with no load.

    If the filter us noisy without the media and trays, then you could possibly have a impeller issue like, broken blade on the impeller or a cracked or worn magnet or shaft. Or it could just simply be dirty and need a good clean out.

    Load shedding and in particular the constant on off pf power tends to reak havoc with canisters, especially older ones. I have lost 2 FX5 in the last 9 months due to load shedding. Both times blown pumps.

    Remember it's easier to suck air that water. Check your seals and inflow connections.

    You could ask at Birdsahaven in Somerset West or at Pets Unleashed (They will be willing to order it for you) Not so much at Petworld XXL.

    Dophin is crap ,got a c1000 and after 4 years it leaks about 2l in 10 minutes with a new seal , Got a 1600 new and it does exactly what you have ... IMHO dophin is poor quality and doesnt last .

    This makes me feel slightly better about my own ability to keep it running. Although I know I’m not the best in the technical department (by no means)

    Dolphin is basically just rebranded Penplax. Which in itself isn't a bad brand. You must just have had bad luck with them. I've been running them for years without issue. But then every brand has its horror stories.

    Made in the exact same factory, has the same naming convention ea 500/700/1000/1500 and the parts are enterchangble. Also they look exactly the same with just a few cosmetic changes.

    Plenty of Chinese manufactures operate in this way.

    100% Dophin is rebranded and is basically Cascade filters. In fact you can 100% inter change parts between them.

    Yup if you remove the branding then it would be almost impossible to tell them appart.

    Rebranded is a fancy phrase for copied . Doesn’t mean it’s the same quality.

    Rebranded, ea they use the exact same factory and the exact same part. The only difference is the colors they use for the plastic and the branding. Most major brands made in China follow this same route. The only brands that don't do that are German brands like Eheim and Aquaclear.
