Hey I played around with out knowing what i was doing and made up this out of piece of 75 x50mm electrical ducting 650mm long, garden hose from in tank filter up through water proof gland into bottom of one end of duct, cut 2 holes in lid ( spaced so i could cut in a third hole later if wanted ) used some hydro growing pots and clay balls from switched on gardner and cut a slot for a waterfall effect back into the tank got some 5 dollar plants from warehouse chucked em in and filled all area around plant baskets with bio noodles.
I made this up purly as a filter and its worked great so far after about a month of running you can see the size difference in the plant on the left
