Boyd Chemi-Pure Elite features the same powerful filtration media as original Chemi-Pure, but with added ferric oxide to remove phosphates, silicates and red slime (cyano-bacteria) for cleaner, clearer water. It also supports aerobic bacteria growth and removes dissolved organics in all aquarium types.

• Superior filter media in durable nylon bag.
• Now with ferric oxide to remove phosphates and silicates.
• For freshwater, marine and reef aquariums.

The Chemi-Pure Elite unique formulation enhances aquarium health and supports longer fish life. It helps eliminate foul odors, removes toxic elements such as copper and phenol, has a safe pH range, reduces water changes and causes no osmotic shock or ion antagonism. It increases appetites of all fish species with no acclimation time, supporting healthy metabolism.
