The Great Big Filter Thread

[BranchScape]

For the Oase I had to clean the impeller monthly once it got to about a year old which is insane. It gets worse over time mainly as I think the mature filter generates more beneficial biofilm for waste processing. Air burping you need to shake it to clear air bubbles out and that takes 10 minutes then you need to have very tight pipe connections. Using silicone hoses seemed to limit new air coming in.. The disconnect for the in/outflow needs to be babied or it will leak. My one glowing review is its prefilter is super easy to clean with less splashing than Aquael where the pressure always means some water splashing, not a lot but some and the canisters are big so moving them to dry it is annoying.

I assume you had impeller hum noise, did you also have burping?

I used to before, but now I routinely shake the canister in all directions after pre filter clean up and that fixed it. As I was deep cleaning the filter, I can see how the rubber valve ring in the prefilter will need to be changed occasionally.
