PURE Marine. Have you tried it yet?

PURE Marine should be used regularly as part of your maintenance program to maintain the biological equilibrium inside your aquarium. PURE Marine can also be used to recover the bacterial balance following a filter crash or to speed up the maturation process in new filters. PURE Marine uses groundbreaking technology to maintain crystal clear and healthy water in marine and reef aquariums.

PURE Marine is a combination of marine-specific bacteria and enzymes that provide many benefits including:
  • Reduces organic waste
  • Maintaining a biological equilibrium
  • Improving nitrification
  • Accelerating maturation process
  • Reducing BOD / DOC / TSS
  • Rapidly restoring equilibrium
  • Reducing filter and skimmer maintenance/cleaning
Product Details:

PURE Marine is a natural product. It is therefore perfectly normal that the balls may vary in size. PURE Marine will respond to the water conditions in each tank . This means that variation in appearance is normal and the rate of change can vary. Each PURE Marine ball is manufactured from a natural polymer and is biodegradable. As with most bacterial products, the manufacturer recommends the addition of air into your tank using an air pump or venturi. Wash hands after use. Keep in a safe place out of the reach of children. If swallowed, drink plenty of water.
