Forum » Filter layers order

hi! i,ve just bought a crystal 4 hydor filter but i´m wondering if i´m puting the filter matherials in right order. I´ve red that first layer is for mechanical and them for biologic, so i thought that the right order, acording to top entrance of water is: wool, sponge and them ceramic (i´m not usin active carbon, so i´ve removed the basket) but...i cannot understand how water flow works...entrance and exit for the water are pretty near...does the water enter by the top, goes down and later goes up again? how do i´ve to put the plastic vertical guide according to the water entrance?(i supose it guides the water somehow) Thanks indeed!!!
