Saltwater & Reef Aquariums

Getting Started with Saltwater Aquariums

Saltwater aquariums bring a piece of the ocean into your home, offering access to vibrant marine fish, stunning corals, and fascinating invertebrates that freshwater systems simply cannot match. While saltwater tanks require more attention to water chemistry and specialized equipment, the rewards of a thriving reef or marine fish-only system make the extra effort worthwhile.

Marine aquariums fall into three main categories: Fish Only (FO) tanks that showcase marine fish with artificial decor, Fish Only With Live Rock (FOWLR) systems that add natural biological filtration, and Reef Tanks that include living corals and invertebrates. Each type has different equipment requirements and care demands, but all share the fundamental need for stable water parameters and proper cycling before adding livestock.

Success in saltwater aquariums comes from understanding the nitrogen cycle, investing in quality equipment like protein skimmers and appropriate lighting, and taking a patient approach to stocking. Marine fish are less tolerant of water parameter fluctuations than freshwater species because ocean environments remain remarkably stable year-round.
