Banana leaves – natural care and decoration for aquariumsBanana leaves are a natural and decorative addition to freshwater aquariums. They are particularly suitable for shrimp aquariums, blackwater setups and naturally themed tanks. Once in the water, the dried leaves slowly release tannins, helping to create a natural aquarium environment. The leaves provide small fish, shrimp, snails and crabs with sheltered areas to hide in. As they gradually decompose, they create valuable grazing areas and a natural food source for shrimp and snails. Banana leaves are also popular in shrimp breeding, as they provide the animals with places to retreat to and additional surfaces for grazing.Banana leaves are an interesting alternative or addition to sea almond leaves and can be combined very well with other natural materials such as catappa bark, coconut shells, lotus pods or cholla wood.Advantages at a glanceNatural leaves for aquariums and shrimp tanksRelease tannins into the waterCan help to support a natural blackwater environmentProvide hiding places for small fish, shrimp, snails and crayfishUsed as grazing and feeding areas whilst decomposingNaturally dried and untreatedSafe for fish, shrimp, crayfish and snailsContents: 20 piecesUsageUse approximately 1 leaf per 5 litres of aquarium water. The leaves can be placed directly into the aquarium. They usually sink after 48–72 hours and remain effective for around 2–3 weeks. Afterwards, the remains can be removed or left in the aquarium as a natural food source for shrimp and snails. Zoo Roco Tip: Combine banana leaves with catappa leaves, coconut shells or moss-covered stones. This will create a natural arrangement with plenty of hiding places, foraging areas and a particularly harmonious look.

Catappa Leaves XL – natural sea almond tree leaves for aquariums and terrariumsCatappa Leaves XL are large, dried leaves of the sea almond tree and are particularly popular in aquariums with tropical fish, shrimp and blackwater species. In water, the leaves release natural tannins and humic substances slowly, which may cause the aquarium water to take on a slightly yellowish to brownish tint.This natural colouring diffuses the light and mimics the habitat of many tropical fish species. As the leaves slowly decompose, they create valuable grazing areas for shrimp, catfish and other aquarium inhabitants. At the same time, the large leaves provide natural cover and places of refuge. Catappa leaves can also be used decoratively in terrariums and serve as hiding places for small animals or as ground decoration. Catappa leaves are a popular natural product for natural-looking aquariums, blackwater setups and biotope tanks. When stored dry, they have a very long shelf life and are easy to use.Advantages at a glanceLarge Catappa leaves with a length of 21–40 cmRelease natural tannins and humic substancesSupport a natural blackwater appearanceCan promote the well-being of fishProvide grazing areas for shrimp and catfishAlso suitable as decoration and hiding place in the terrarium100 % natural product UsageThe leaves can be placed directly into the aquarium. They soak up water and sink to the bottom after some time. There they release their natural substances over several weeks. After about two to three weeks, a new leaf can be added if needed. The old leaves can remain in the aquarium, as they are readily grazed on by shrimp and other animals.Product detailsSize: approx. 21–40 cmContents: 10 piecesMaterial: dried leaves of the sea almond tree, Terminalia catappaSuitable for: freshwater aquariums, blackwater tanks, shrimp aquariums and terrariumsZoo Roco Tip: Catappa Leaves XL can be ideally combined with alder cones, lotus pods, cholla wood or coconut shells. This creates a particularly natural-looking aquarium with many hiding places and valuable surfaces for grazing.

Aqua Rebell Makro Spezial NPK Soil Aqua Rebell Makro Spezial NPK Soil is a liquid macronutrient fertiliser for planted aquariums, particularly for aquascapes with active soil substrate. The fertiliser specifically supplies aquatic plants with the essential macronutrients nitrogen, phosphate and potassium. The special formulation is nitrogen-rich, phosphate-limited and potassium-enriched. This makes the fertiliser particularly well-suited to aquariums with soil, as it supports nutrient supply without unnecessarily affecting the natural nutrient dynamics of the substrate. The result is vigorous, robust and relatively compact plant growth.The ready-to-use liquid fertiliser is easy to dose and can be individually adjusted depending on plant density, lighting, CO₂ supply and nutrient consumption. NPK Soil can also be used in aquariums without soil if a controlled supply of macronutrients with reduced phosphate input is desired. For optimum results, we recommend combining it with a suitable micronutrient fertiliser to supply iron and trace elements, for example Aqua Rebell Mikro Spezial Flowgrow.Advantages at a glanceMacronutrient fertiliser containing nitrogen, phosphate and potassiumSpecially developed for planted aquariums with soil substrateNitrogen-rich and phosphate-limited formulationEnriched with potassium for a balanced supplyPromotes vigorous, healthy and compact plant growthAlso suitable for aquariums without soil, if controlled fertilisation is desiredLiquid and ready to useContents: 500 ml or 1000mlUsage and instructionsWeekly water changes of 25 to 50 % are recommended. The dosage can be increased or reduced depending on the aquarium. If nitrate or phosphate levels are already high, the fertiliser should be used with great caution or not at all. If nitrate or phosphate levels rise too sharply as a result of fertilisation, the dosage should be reduced accordingly. A CO₂ concentration of around 20 mg/l can help to promote vigorous plant growth.Zoo Roco Tip: At the start, check nitrate, phosphate and potassium levels regularly to find the right dosage for your aquarium. When used in combination with an iron and trace element fertiliser, this provides a complete nutrient supply for healthy aquarium plants.
