AAP recommends our "Aquarium Filtration" article

Here is an excerpt from the section about Under Gravel Filters (often a very misunderstood filter):
"UNDER GRAVEL (UGF);
An old standby that is good for biological filtration (the conversion of fish waste from ammonia and nitrites to less harmful nitrates), but is poor to fair for mechanical filtration (the removal of debris- organic and inorganic).
For biological filtration the under-gravel filter still has some drawbacks to consider too, but generally when used in an incorrect application.
It is noteworthy that I set up the entire Bahooka Restaurant (this restaurant was featured in "Fear and Loathing in Las Vegas" and had 110+ aquariums, most over 75 gallons) with only under-gravel filters and they preformed well under the proper care and optimum conditions for this type of filter (some even planted too)."
