Sicce ZeroPhos is a phosphate-removing resin for freshwater aquariums. Phosphate builds up from leftover food, decaying plants and fish waste. A small amount helps plants grow, but too much feeds nuisance algae, which looks untidy and can compete with your plants.

ZeroPhos is designed to start lowering phosphate within about 48 hours, then keeps working to hold it at a level that still suits plants. It doesn’t alter pH, and it also helps reduce dissolved silicates, another nutrient linked to algae.

Key Features

• Removes phosphate: Helps lower excess phosphate in aquarium water.
• Fast acting: Designed to start working within about 48 hours.

• Reduces silicates: Also helps lower dissolved silicates.
