New to canister filters. Decided it was time to clean the filter. Used tank water and ensured impeller was clean. Also changed filter floss. Flow doesn't seem as good and 48 hours later the water just seems to be getting cloudier. I have no clue what's gone wrong. As I have quite a powerful bubbler to oxygenate, should I turn the spray bar to point down slightly?? Water was crystal clear before I did the maintenance
