ok.. I just found out that my return pump runs about 600gph but my overflow only runs about 300gph..(I think) since it says PF-300 on the model.. anyways is there anyway I can balance this thing out?.. or is it ok that my pump is stronger... I have heard of people using valves but I read on most sites that its not a good idea to use it as it should always be fully open.. Thanks in Advance!!!!!
