Considered the most effective phosphate/silicate remover by many expert aquarists, ROWAphos is specially designed to be used with a fluidized reactor. Perfect for fragile reef systems, ROWAphos is gentle and will not shock the animals in your aquarium. ROWAphos will never release anything back into the water: no matter how long it's in your aquarium.
Specifications Package Size 500 ML
Instructions Can be used in a canister filter as a separate slow phosphate filter or can be utilized at the end of the main filter system as the final stage after the biological and mechanical filters. This media can be used in a very fine filter bag or sandwiched between two layers of fine filter floss (on the incoming or outgoing flow). The amount required will be determined by both the level of phosphate in the water and the level of phosphate in the rocks, gravel and other substrates within the aquarium.
In new or established aquariums where the phosphate levels are high, first measure the level in the water and assume that 2-4 times that amount may be bound up in the substrate and adjust by dividing the recommended aquarium size by 2-4 times.

Do not rinse before use. In some cases the use of this product can turn the aquarium water slightly brown in color due to the dislocation of finer particles of the material. This is completely harmless for fish or any other organisms and will disappear after a short period. Note: Do not sprinkle product directly into the aquarium. Never place directly into water without first surrounding it with a sponge or filter floss.
