Caribsea ARM Reactor Media 3.8L

Caribsea ARM Reactor Media

Caribsea ARM Reactor Media is a calcium reactor media for marine aquarium keepers using a calcium reactor to add calcium, carbonate and essential trace elements to their aquarium water. The supplied product information identifies this ARM media as CaribSea ARM Extra Coarse Reactor Media, a precision-graded option designed for strong carbon dioxide penetration and lower-maintenance reactor operation.

Key Benefits

• Provides calcium, carbonate and essential trace elements as a complete calcium reactor media solution.
• Contains nearly 50 times the strontium of other brands, with 7390 ppm stated strontium content.
• Precision grading supports maximum carbon dioxide penetration through the media.
• Contains no gastropod shells, helping it achieve a very low phosphate content of less than 1/10th of 1 ppm.
• Offers high solubility and is stated to be metastable at 8.2.
• Extra Coarse granules are the largest of the ARM grades and are the least likely to clog reactor equipment, making them the lowest-maintenance option.
• ARM is described as one of the most trusted reactor media options in the calcium reactor industry.

How to Use

• Use as reactor media in a calcium reactor.
• Allow carbon dioxide to penetrate the precision-graded media so that calcium, carbonate and trace elements can be supplied through the reactor system.
• Select the ARM granule grade according to the surface area and maintenance requirements of the reactor setup.

Suitable For

• Marine aquariums operated with a calcium reactor.
• Aquarium keepers looking for reactor media containing calcium, carbonate and essential trace elements.
• Reactor systems where larger granules and reduced likelihood of clogging are preferred.

Specifications

• Brand: CaribSea.
• Product type: Calcium reactor media / filter media.
• Grade identified in the supplied information: Extra Coarse.
• Strontium: 7390 ppm.
• Phosphate content: less than 1/10th of 1 ppm.
• Solubility statement: metastable at 8.2.
• ARM media grades: Small, Coarse and Extra Coarse.
• Small grade provides the greatest surface area, maximising the amount of calcium and carbonate that can be added to the tank; however, it can clog many reactors and may require ongoing maintenance.
• Coarse grade uses larger granules that are less likely to clog equipment.
• Extra Coarse uses the largest granules and is least likely to clog equipment, resulting in the lowest-maintenance ARM option.
• All ARM media is packaged by volume in a 1-gallon container. Weight may vary from container to container.

What's Included

• Caribsea ARM Reactor Media, 3.8L (1 gallon) container.

Frequently Asked Questions

What is Caribsea ARM Reactor Media used for?
It is used in a calcium reactor to provide calcium, carbonate and essential trace elements for a marine aquarium.

Why is the Extra Coarse ARM grade useful?
Extra Coarse is the largest ARM granule grade. It is least likely to clog reactor equipment and is described as the lowest-maintenance option.

Does this reactor media contain phosphate?
The supplied information states a low phosphate content of less than 1/10th of 1 ppm, with no gastropod shells used in the media.

What is the stated strontium content of ARM Reactor Media?
It contains 7390 ppm of strontium, stated as nearly 50 times the strontium of other brands.

How do the Small, Coarse and Extra Coarse ARM grades differ?
Small offers the most surface area but can clog many reactors; Coarse has larger granules that are less likely to clog; and Extra Coarse has the largest granules and the lowest likelihood of clogging.

Why can the weight of ARM media containers vary?
ARM media is packaged by volume in a 1-gallon container, so the weight may vary from one container to another.
