Effectively reduce phosphate and silicate for a cleaner, healthier aquarium.
Waterbox Freshwater Phosphate Media is a highly efficient filtration media designed to absorb and remove excess phosphate and silicate from your aquarium water. Elevated phosphate levels can lead to unwanted algae growth, cloudy water, and reduced water quality in both fish-only and planted aquariums.
By maintaining phosphate within the proper range, this media helps create a cleaner, clearer, and more balanced environment for fish and plants alike. Regular use as part of your filtration system supports long-term water quality and helps prevent the conditions that promote nuisance algae.
Key Benefits:
• Rapidly absorbs excess phosphate and silicate
• Helps prevent algae growth and water discoloration
• Promotes a balanced, low-nutrient environment
• Improves water clarity and overall aquarium health
• Ideal for both fish-only and planted freshwater aquariums
Directions for Use:
Use 50 ml of media per 100 L (25 gal) of aquarium water.
Place in a canister filter or media bag with adequate water flow.
Replace media monthly or as phosphate levels begin to rise.
