    Questions and answers

    What is Aquarium Systems best known for?
    Its sea salts: Instant Ocean for fish-only and general marine tanks, and Reef Crystals, which carries raised calcium and trace elements for reef tanks. Its hydrometers and refractometers are also widely used for checking salinity.
    Which salt should I pick, Instant Ocean or Reef Crystals?
    Instant Ocean suits fish-only and simple marine setups and dissolves cleanly. Reef Crystals mixes to higher calcium, alkalinity and magnesium levels, which helps stony corals and clams that draw those elements down.
    Does Aquarium Systems offer a warranty?
    Warranty terms come from the retailer or distributor that sells the item, not from the brand page here. Check the terms with the store you buy from before ordering, especially on refractometers and test kits.
    How do I return an Aquarium Systems product?
    Returns go through the store you bought from, so its return window and conditions apply. Opened salt mixes and used test kits are often excluded, so confirm the policy first.
    When does Aquarium Systems go on sale?
    Marine-supply stores tend to discount salt buckets and starter kits around tank-setup season and major holiday events. The page tracks each store's price history, so you can see when a store has moved its own price.
    Are there Aquarium Systems discount codes?
    Deal.ai checks what Aquarium Systems products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
