sera Catappa Leaves XXL 32 cm, pack of 10 – aquarium almond leaves for water conditioning

sera Catappa Leaves XXL are high-quality, natural almond leaves specifically selected for aquarium water conditioning. Measuring approximately 32 cm in length, these leaves are a premium choice for aquarists looking to replicate natural tropical biotope conditions. As they slowly decompose in the water, they release valuable tannins and humic substances that gently lower the pH level and create a mildly acidic environment, which is highly beneficial for the health and well-being of many freshwater fish and shrimp species.

Advantages

The primary benefit of using these natural leaves is their ability to create a protective, antimicrobial environment that supports the immune system of aquatic inhabitants. By releasing natural compounds, they help to reduce stress in fish and shrimp, making them particularly effective during the acclimation process or when introducing new livestock to the tank. Furthermore, these leaves provide a natural food source for shrimp and microorganisms, while their presence encourages natural behavior and breeding success in sensitive species.

Suitable for

• Freshwater aquariums aiming for a natural biotope look
• Breeding tanks for sensitive fish and shrimp species
• Reducing stress during transport or acclimation
• Supporting the health of fish prone to fungal or bacterial infections

When it may not be suitable

These leaves are not recommended for aquariums that require a high pH or alkaline water chemistry, as the tannins will naturally acidify the water. Additionally, they may not be suitable for tanks with very high filtration rates that remove organic substances too quickly, or for aquarists who prefer a crystal-clear, sterile aesthetic, as the leaves will tint the water a light amber color.

Key specifications

• Material: 100% natural Terminalia catappa leaves
• Size: Approximately 32 cm per leaf
• Quantity: 10 leaves per pack
• Effect: Releases tannins and humic substances
• Water impact: Mildly acidifies water and provides antimicrobial properties

How to use

To use the leaves, simply place one or more directly into the aquarium. They will initially float on the surface before gradually absorbing water and sinking to the bottom. Once submerged, they will begin to release their active ingredients into the water column. You can leave the leaves in the tank until they have completely decomposed, at which point they can be replaced with fresh ones to maintain the desired water conditions.

What to consider before purchase

• The water will take on a light tea-colored tint due to the release of tannins
• The leaves are a natural product and may vary slightly in size and shape
• Monitor pH levels if you have a small aquarium with low buffering capacity
• Ensure your aquarium filter does not contain chemical media like activated carbon that would neutralize the tannins

Usage recommendations

For optimal results, start with one leaf per 50-100 liters of water and observe the reaction of your livestock. You can increase the dosage gradually if you wish to achieve a darker, more concentrated biotope effect.
