I used to do that monthly to most of my pumps as a preventive measure, it was a pain.
My first aquarium was a 90 gallon reef filtered with a Skilter 400 power filter (similar to yours), a Marineland magnum carbon canister with dual bio wheels, a small uv sterilizer, and what really saved me... in excess of 100 pounds of premium Fiji live rock.
I've tried a variety of filtering methods with different setups, it's amazing how sw has progressed with that. My last aquarium was a 92 gallon corner tank. Live sand bed with an anaerobic plenum, around 100 pounds of live rock, closed loop pumps for extra circulation, Vortech MP pumps for tidal simulation on a controller, built in overflow piped through a wall into a nearby closet to a 75 gallon sump, massive crazy protein skimmer, geo carbon reactor, phosphate reactor, uv sterilizer, a large refugium filled with pods & macro algae, automatic reverse osmosis top off, Metal halide lighting for the display tank, power compact light over the refugium for good algae growth and ph balancing, dual medical dosing pumps, and just about everything was computer controlled!
