Brightwell Aquatics HeXiDiscs - Hexagonal Coral Frag Mounts for Marine Aquariums, Encourages Bacteria and Nutrient Growth, 100 Count

• Combines the benefits of large surface area with aragonite component to maximize the use of available space in coral culture systems while maximizing the growth rate potential of coralline algae.
• Hexagonal shape of HeXiDiscs allows for close placement on flat surfaces to maximize use of available surface area in grow out systems; more efficient than round frag discs.
• Hexagonal shape is conducive to growing all manner of branching, plating, and massive stony corals, soft corals, and colonial polyps such as zoanthids and their close allies.
• Made of Xport CA material: large surface area encourages colonization by beneficial nitrifying bacteria, resulting in rapid conversion of ammonia into nitrite and nitrate and enhancing the stability of nutrient concentrations.
