The 1 Gallon ARM Reactor Media Coarse is a highly regarded calcium reactor media specifically formulated for saltwater reef aquariums. It serves as a complete solution, providing essential calcium, carbonate, and a comprehensive blend of trace elements to maintain stable water chemistry, crucial for the health and growth of corals and other calcifying organisms. Designed for use in calcium reactors, this media efficiently replenishes minerals consumed in the reef environment, helping to stabilize alkalinity and calcium levels.

This coarse-grade media boasts nearly 50 times the strontium of other brands, clocking in at an impressive 7390ppm, and ensures extremely low phosphate content (less than 1/10th of 1ppm) due to the absence of gastropod shells. Its precision grading allows for maximum carbon dioxide penetration, enhancing efficiency, while its highest solubility, metastable at 8.2, ensures optimal performance. The coarse granule size is specifically chosen to reduce the likelihood of clogging equipment, contributing to lower maintenance requirements. Each package is volume-measured at 1 gallon, with weights averaging between 8 to 10 pounds of media.

This product is an excellent choice for reef aquarium hobbyists utilizing calcium reactors who seek a reliable, high-performance, and low-maintenance solution for their tank's mineral demands. It is particularly beneficial for systems with a high bioload of calcifying corals, or for those aiming to achieve exceptionally stable water parameters with a trusted, industry-standard media. Its robust composition and anti-clogging properties make it a smart investment for maintaining a thriving reef environment.
