Bro ngjaso, I used to run a similar canister filter set up to you but have since decommed it last weekend.
It was decommed because I can't seem to get rid of my algae bloom no matter what I did and my canister seems to be the main culprit.
Although the results were expected, it was way better then expected. Been 5 days and I have not seen any algae growing on my glass since I cleaned it off when I decom the canister. In the past algae would start growing 1-2 days after a clean up.
When I first hooked up the canister, algae was not blooming so quickly. But as time went by it really bloomed non stop. My guess is due to the dirt trapped inside the canister. Now I'm happy to be back to a non-algae blooming tank.
