Oxygen Block 20g

The Serenity Oxygen Block (20g) is an aquarium water treatment that slowly dissolves in water to replenish dissolved oxygen and stabilize pH levels. It is highly effective for maintaining a healthy aquatic environment or keeping fish oxygenated during transport.

Key Features & Benefits:

• Slow Dissolve: Gradually releases ingredients to provide a continuous, vital oxygen supply.

• pH Stabilization: Helps stabilize the water's pH balance.

• Fish Health: Reduces stress and prevents fish from becoming oxygen-starved.

• Transportation: Ideal for keeping oxygen levels stable in fish transport bags and containers.

• Simply place the block directly into your aquarium or small pond.

• Replace with a new block once it has almost fully dissolved.
