This replacement sponge ensures optimal filtration performance, helping maintain a clean and healthy aquarium environment for your fish. It is specially designed to trap debris and organic matter, providing both mechanical and biological filtration. With easy installation and superior durability, this sponge is a must-have for keeping your tank’s water pristine and your aquatic life thriving.

Key Features & Benefits:

• Perfect Fit for Hydra Filters: The OF Ocean Free Replacement Sponge is designed specifically for the Hydra 20, 30, 40, and 50 internal filter models. It fits securely in the filter compartment, making installation hassle-free and ensuring efficient filtration.

• Mechanical Filtration: The sponge captures large debris like fish waste, uneaten food, and plant matter, preventing clogging and keeping your tank clear. This type of filtration helps reduce the build-up of harmful particles, ensuring the water remains clean and oxygen-rich.

• Biological Filtration: The sponge's porous structure provides an ideal surface for beneficial bacteria to colonize. These bacteria break down harmful ammonia and nitrites, converting them into safer compounds, which is essential for the nitrogen cycle in your aquarium.

• Durable and Long-Lasting: Made from high-quality, non-toxic materials, this sponge is built to withstand long-term use without deteriorating. It’s easy to rinse and reuse, maintaining its structure and functionality for an extended period.

• Easy to Install and Replace: Simply remove the old sponge from your Hydra filter and replace it with the new OF Ocean Free sponge. No tools are required, and the process is quick and straightforward, ensuring your filter keeps running smoothly.

• Optimizes Water Quality: Regular replacement of the filter sponge ensures consistent water quality, which is vital for the health of your fish. By improving the filter’s efficiency, it helps maintain an optimal balance of water parameters, ensuring a safe environment for your aquarium’s inhabitants.

• Suitable for Freshwater and Marine Aquariums: The OF Ocean Free Replacement Sponge is versatile and can be used in both freshwater and marine tanks. It helps maintain stable water conditions for a variety of aquatic species.

Water Conditions:

• pH Range: Suitable for both acidic and slightly alkaline water, the replacement sponge helps filter water in a variety of pH conditions, from 6.0 to 8.0.
• Temperature Range: It works effectively within a temperature range of 22°C to 28°C (72°F to 82°F), making it ideal for most tropical and subtropical fish species.
• Hardness: Works well in soft to moderately hard water, ensuring that filtration performance is not compromised under various water hardness levels.

Tank Mates:

• This replacement sponge is designed for a wide range of tank mates, from small tropical fish like tetras and guppies to larger fish species. Whether you have a community tank or a species-specific tank, the sponge helps maintain clean water for both peaceful and semi-aggressive species.
• The sponge is especially beneficial in tanks housing delicate or high-maintenance fish, such as discus, bettas, and angelfish, where water quality is crucial for their well-being.

Feeding Habits:

• The filter sponge helps manage uneaten food, preventing it from decaying in the tank and leading to poor water quality. Proper filtration encourages efficient food consumption and reduces the likelihood of excess feed becoming trapped in the substrate.
• For tanks with herbivorous or omnivorous fish, such as plecos and mollies, the sponge will capture plant matter and any leftover organic material to maintain cleanliness.
• For carnivorous species, such as predatory fish, the sponge assists in collecting leftover meaty foods, keeping the tank’s environment healthy and preventing foul smells from rotting food.

Care and Maintenance:

• Regular Cleaning: Rinse the sponge every 1-2 weeks with aquarium water (not tap water) to remove trapped debris and prevent clogging. This keeps your filter running efficiently.
• Replace as Needed: Although durable, the sponge will eventually need to be replaced after months of use. Keeping an extra OF Ocean Free Replacement Sponge on hand ensures you always have a replacement ready.
• Avoid Over-Cleaning: Do not over-clean the sponge, as it could disrupt the beneficial bacteria colony responsible for biological filtration. Clean gently and avoid using harsh chemicals.
