Im getting mixed reviews. Directions say to remove foam filter pads before backwashing and a few different pond store owners say thats not necessary. Obviously someone on here is going to say follow the directions of the filter. Thats a given....BUT several experienced pond owners are telling me differently and its a pain in the neck to get to the filters just to backwash so if I dont have to Id like to lean towards not. I am not lazy and would take the filters out but if its generally not necessary id rather not keep opening and closing plastic and rubber parts so they wear out faster. Any experienced insight (not an obvious opinion telling me to follow the directions) will be extremely appreciated...
