The successful aquarist realizes the importance of establishing the nitrogen cycle quickly and with minimal stress on the aquarium’s inhabitants. Aquarium filtration has advanced from the old box filters filled with charcoal and glass wool to undergravel filters, then trickle filters, and most recently – fluidized bed filters.

The availability of advanced high-tech filtration systems has lent added importance to the understanding of basic aquatic chemistry.
