1 Gallon ARM Reactor Media – Coarse

ARM Coarse Reactor Media contains calcium, carbonate, and trace elements.

• Nearly 50x the Strontium of other brands (7390ppm)
• Precision grading allows for maximum carbon dioxide penetration
• No gastropod shells means the lowest phosphate content (less than 1/10th of 1ppm)
• Highest solubility of any reactor media (metastable at 8.2)

One of the most trusted media for calcium reactors in the industry. The media is a complete solution which includes both calcium and carbonate as well as essential trace elements.

The media comes in two forms Coarse and Extra Coarse.

• Coarse – larger size granules which are less likely to clog equipment.
• Extra Coarse – Largest size granules and the least likely to clog equipment which results in the lowest maintenance option.

Note: All ARM media is packaged by volume in a 1-gallon container. Weights may vary from container to container, but on average one gallon will yield 8 – 10 pounds of media.
