What is Aquarium Systems Reef Crystals Salt?

Aquarium Systems Reef Crystals salt is a sea salt mix created from enriched seawater that offers many benefits to reef organisms. It contains a blend of calcium, essential trace elements, additional vitamins and a neutraliser which all work together to mimic natural seawater, ideal for growing healthy, strong corals. The additional calcium aids in skeletal structure development and is particularly good for stony corals and coralline algae.

Why do I need salt for my reef aquarium?

An aquarium containing animals and reef life quickly depletes nutrients from the water, so it is essential to replenish these levels for growth. To maintain water quality, reef aquarium enthusiasts must mix salt into their purified water that contains additional trace elements. Reef Crystals sea salt is perfect for this and will keep refined reef tanks looking their best with regular top-ups.
