There are also many threads on here you can follow and read, plus these guys love posting pics of there stuff..alot of different ideas, one is bound to suite your needs and wallet.It's a natural filtration system. I use cheto algae and a in tank protein skimmer as my main 2 filtration. I do low dosing NoPox because I want my nitrates to stay elevated between 5ppm and 10ppm. Just Google it.. you can always buy books about aquarium filtration also, that's how I learned to make mine, reading lots of books.especially books written by Mr Fenner, Mr. Sprung, Mr. Delbreek, and many more.
