Building a 5gallon bucket canister filter for the 75, and don’t know what the appropriate gph would be for something like that. Any thoughts guys?

Some of it will depend on the length of our hoses, and how much turnover you want in the filter.

Higher flow will promote mostly mechanical filtration, lower flow will help with biological filtration. Types of media will affect the flow rate.

Can't provide any concrete numbers, just some things to consider that will help narrow down an answer.
