I wonder why (and when) filter polishing is required.
Thats really what it is all about for me; that extra bit of clarity mostly for aesthetics, but yes, it also traps algae spores that are always present in the water column. If you have hazy water due to bacterial bloom or suspended organic waste due to imbalance or lack of maintenance etc., deploying polishing pads should probably not be your first course of action.... but to some, there is a difference between 'clear' and 'crystal clear')
Cheers,
