trying to set up 300 gal rubber maids for my rays
will be running fx5 and wanting to add a second filter has to be gravity fed do to limited space. like the fact that it has a built in uv recommended a max flow of 1200 per gal. what size pump would you run i want the uv to work sufficient. are these any good? any suggestions
