An effective means for fluidization filters.

PH Minus is an effective solution for controlling phosphate and silicate levels in marine aquariums, thanks to its unique adsorption technology. Excess food and supplements can lead to high phosphate levels, but with PH Minus you can effectively reduce these levels without harming your aquarium inhabitants.

Improve the water quality of your marine aquarium by reducing phosphate and silicate levels with PH Less!

Phosphate Minus is recommended for use in new and mature aquariums. In newly installed aquariums it prevents phosphate buildup while in older aquariums it reduces PO4 levels and stabilizes water composition. By maintaining a biological balance in the tank, it prevents the growth of unwanted green algae and the formation of cyanobacteria.

Maintain balanced water conditions.

Dosage : 25-100 ml per 100 l (27 US gals) of water. Phosphate minus should be placed in media reactors with a suggested water flow of at least 400 l/h. It is also suitable for passive use in filter socks. Phosphate minus should be replaced every 4 weeks or when there is a significant increase in phosphate levels in the water. Shortly after being placed in a filtration system, the product may slightly color the water. Although Phosphate Minus should not be rinsed before use, the brown dust is an active phosphate remover and is completely harmless to aquatic life. The brown color of the water will disappear after a short time. Rinsing the product in RODI water will reduce its effectiveness.
