I am trying to set up this diffuser
to be inline with this pump.
This is going in the back of a 24 gallon AquaPod. The filter is built into the back section of the tank, so no canister. It's a little tight, but i can fit it in there, with the right adapters. the ones that came with the diffuser are too small.

Any ideas? Thanks for the help!
