Bacteria grow on and consume the biodegradable carbon Pearls and at the same time remove nitrate and phosphate from the aquarium water.--Use of a reactor to keep the media tumbling is highly recommended. Replenish the Pearls at regular intervals.
Imagine if you could be satisfied and content with your purchase. That can very much be your reality with the NP-Active Pearls 450ml for your aquarium.
