Air pump/stone when using canister filters?

You need an air pump if dissolved oxygen level is low.
While using certain types of filters setup in certain ways may affect ORP, it's not a Yes/No variable.

I've just switched from a couple of penguin 350's w/bio wheels to Rena XP3 canisters. I had surface agitation before w/the wheels, but nothing now.. Thought I'd ask. Thanks.
I think its always best to have at least one airstone, even if you have plenty of flow. an airstone keeps the water from "stratifying" or seperating into layers & keeps it well mixed. Surface agitation is also a bonus. Stratification can cause the water at the bottom of the tank to be colder, stagnant & low in oxygen.
Howdy,
I have been running canisters for decades, and never needed an airstone... just position your spray bar above the water level, that'll aerate plenty! BTW: Don't aerate if you have plants!

x2 on this . . . if you position the spray bar above the water level, it creates surface agitation, which serves the same purpose as an airstone.
I don't do that because I have plants, and also because it makes a fair amount of noise . . . but you can do it
