Yup, just like a wet dry with bioballs.. Only larger, better have a very good prefilter inline and change often... They used to call them spray bars. They need to be cleaned regularly or they will clog up.. Make sure the size of the intake line isn't larger than the spray bar holes or they will clog up sooner....
