Reef & Saltwater

Saltwater and reef tanks ask for more precise water chemistry and equipment than most freshwater setups. This section starts with guides on routine care and nitrates, and equipment articles follow as they are published. Our guides cite manufacturer or university sources and do not replace advice from a licensed aquatic veterinarian or your livestock supplier.

Salinity, alkalinity, and nutrient targets vary by livestock, so we give each source and avoid one-size-fits-all numbers.

Start with the saltwater tank maintenance guide and the reef tank nitrates guide.
