Aquarium Advice Apprentice
Freshwater filtration. (sorry SW, but my waste water books just don't cover that topic... unless you want me to change it into freshwater.)
Freshwater filtration has 3 normal stages.
Mechanical: this basically removal of large suspended particles. A medium to fine sponge will accomplish this easily. 20NM for average aquariums is my recommendation. 10NM for fine particles and higher water quality.
Biological: This requires a surface area for bacteria to grow. I perfer to use bio balls or another form of suspension media. Bio balls seem to give the best surface area and are easily cleaned.
Chemical: This normally takes the form of activated carbon. Activated carbon will remove chemicals from the water absorbing the chemicals into itself.
My Design: I prefer to use only mechanical and biological. This is because you should not need chemical unless your treating something in your tank or have just added new drift wood or rocks. Otherwise I recommend against chemical treatment. Keep activated carbon around, you will need it occasionally but as a primary treatment, no.
First I took an Aqua tech 5-15. These are about 10 dollars at walmart. That makes it an excellent filter to make mistakes on. I also go some flat sponges and bio balls from my LFS total was $10 again.
Below I will explain how I made the filter and add pictures.
