This is a cheesy attempt to explain the filters I use. You can make them in any size. The ones I make are in 5" pots.
Take a submersible pump and put it in the bottom of a plastic plant pot (the ones that they sell for pond plants that have no holes in the bottom work best) or just cover the holes.
Place in some lava rock (I like to crush mine into grape size pieces) This will act as your biofilter and provide ample surface area for nitrifying bacteria to grow. Oh, and wash the rock well.
Then place a filter bag, which can be found at most pet stores, filled with carbon, in next. (pantyhose works just as well and is cheaper)
Then Cut a poly filterpad to fit snug to the diameter of the pot. Then cut a small hole for the outflow tube.(Do what you will with that. Make a waterfall, leave it be, it doesn’t matter.
Plug it in and enjoy. On the 29 gallon tank I have, I use a 75GPH pump in a 5" pot and it works wonders. As stated before, it can be scaled up for larger quantities of water. This filter will cost less and work longer and more efficiently than almost any submersible filters on the market. The part not to skimp on is the pump. The Filter will last as long as your pump will. Just wash out the filter pad and replace the carbon periodically. Simple enough?
