An Article Discussing The Fifteen Most Common Problems In The Tropical Marine Tank.

In the main, marine fishkeeping is not difficult. But common problems do occur from time to time and although these tend to be of an elementary nature, a significant number of aquarists find difficulty in resolving them unless they have definite and reliable guidelines to refer to.
