Is it better to run 1 large filter, or 2 smaller filters?
Example, Assuming all else is equal, is it better for run 1 filter at 500/gph or 2 filters at 250/gph?
Im in this situation now, where I'm unhappy with my circulation and do not know where to get a bigger replacement unit or a equal second one.
