Author Ray Hunziker, longtime editor of Tropical Fish Hobbyist magazine and lifelong fish keeper, is the ideal tutor for aquarists looking to take a dive into the saltwater end of the tank. Marine Aquariums begins with a discussion of seawater and water quality, the most critical part of keeping marine fishes happily swimming (and breathing) in their tank. Hunziker continues with a step-by-step explanation of setting up a marine aquarium, discussing aquarium types, the number of fishes for the size tank selected, siting the tank, stands, substrates, temperature, lighting, filtration and decor.
