Ziss bubbler bio moving bed filter suction cups

[Steven Fletcher]

I was wondering if anyone knew where to buy replacement suction cups for the Ziss bubbler bio moving bed filter. Mine are finally starting to fail. I'm still able to push it back on the glass but it eventually will lose suction and I'll find it floating in the tank. 

Thanks in advance!

I don't have the Ziss one but a knockoff sold on Amazon. It uses relatively common sized suction cups like those used for airline tubing. Just pop out the airline tubing holder and attach the suction cup to the filter. Some hot melt glue can quickly adhere them if the shaft opening is too big, or aquarium safe epoxy putty or gel super glue would also work to attach them to the filter. The airline suction cups tend to be cheap and readily available. Also, heck to be sure your aquarium wall is really clean. It's possible there's some small debris/biofilm built up that's letting the suction fail and the current cups are fine.

That's a good idea! And I'll definitely try cleaning the glass. I don't know why I didn't think of that lol. Thank you!
