+1. Since this is in the Reef Aquaria section, I'm assuming this isn't for a FOWLR
When a canister filter traps solids, the water flow is still moving across them, and as they decay, it contribute to the nitrates & phosphates in the system. There are
healthy systems with canisters, but you must be very diligent in your maintenance routine & clean them on a regular basis without fail.
A much better option is a sump with a filter sock, a good quality skimmer, and a refugium. The filter sock catches course detritus the same as a canister, but it's MUCH
easier to change out a filter sock every couple/few days rather than repeatedly having to tear apart a canister. A skimmer filters out much finer particulates and deposits them into a collection cup, thus isolating
them away from the water column, and a refugium with some macro algae help consume excess nutrients to prevent algae in your DT.
If you can't do a sump, IMO
your best option is a good HOB
skimmer & regular pwc
's, but you are at "that" size where a sump begins to almost become a necessity for a healthy system.
