Other types of filtration

-
There are also some additional kinds of filters. Foam fractionators pass a large stream of
bubbles through a column of water. Many substances will stick to the foam that collects
at the top, and can thus be removed. Passing ozone and ultraviolet light through aquarium
water are also effective to kill bacteria, algae and parasites. But, these are methods that
have got different levels of endorsements from aquarists. While some swear by these
methods, others say that ozone and ultraviolet rays do nothing for the aquaria. None of
these methods can be recommended to the beginner aquarist as they are expensive and
there usefulness unverified.
For effective filtration, you must take the size of your aquarium into account and use a
combination of the filtration methods described above.
