Tanks for marine aquaria should ideally be a minimum of 50 gals. This improves the stability of the water conditions and allows a number of fish etc. to be kept. Marine stocking levels are far lower than freshwater and small tanks simply don't hold enough fish! There are different types of marine set-ups, detailed below, but all rely on good filtration and Protein Skimming. Protein skimmers work by mixing fine air bubbles with water. The bubble's surface attracts and holds protein and other organic wastes. These form a scum that rises to the surface where it overflows into a collection cup for disposal. Always get the biggest and best skimmer you can!
