Ok- Its fluval canister which will be for you a challenge. I recommend to add a hang on Power filter which will add to water movement but also polish the water. The challenge with canister unit are they often dont keep up with needs of a tank as its a mechanical filter and you want to have mechanical , biological and chemical to manage proper water quality. The trap particles via the foam, etc but needs regular Maintenance often reducing any bacteria that has built up.
Chemical is what traps and breaks down chemical compounds such as feces and uneaten food often accomplished carbon and GFO
Biological is what utilizes the natural process of biological filtration such as use of ceramic nuggets, bio blocks, and microscopic bacteria surfaces as examples. Best it to add or use a hang on refugium such as Reef octopus or AquaMaxx unit and even add a hang on skimmer such as ice cap K1- or K2 100 to cover filtration needs
