SURE-PURE

NP-Active Pearls are a pure, specially made biodegradable carbon for use in aquaria.

They are polymers with the technical name poly hydroxyalkanoates, commonly referred to as PHA.

PHAs are made from bacteria so they are truly 100% natural and completely biodegradable into carbon dioxide and water.

NP-Active Pearls remove nitrate and phosphate from your aquarium water so these nutrients are not available to algae and other nuisances.
