Markro Special Fertilizer N from Aqua RebellNitrogen fertilizer for heavily planted aquariums Aqua Rebell Makro Special N is a high-quality nitrogen fertilizer that has been specially developed for planted aquariums with high nutrient requirements. It ensures healthy plant growth, strong leaf colouring and a stable nutrient supply - especially in heavily lit or CO₂-optimized aquascapes. While many aquariums receive sufficient phosphate and potassium through fish stocking, there is often a nitrogen deficiency. Aqua Rebell Makro Special N provides a targeted remedy here: it supplies plant-available nitrate nitrogen in a balanced concentration without unnecessarily polluting the water. Properties: Highly effective nitrate-based nitrogen fertilizer (no ammonium!) Supports healthy, vigorous plant growth Ideal for low fish loads or heavy planting Simple dosing with integrated dosing aid Made in Germany - highest quality and purity Recommended use: Dose daily or several times a week as required. The recommended daily dose is approx. 1 ml per 50 liters of aquarium water, which adds approx. 1 mg/l nitrate. Regular water analyses help to optimally control the nutrient content.

JBL CO₂ Direct Test Set - Quick test to determine the carbon dioxide content in freshwater aquariums, CO2 Direct Test-Set Simple and reliable control of the water values of aquariums. Determines the optimal carbon dioxide content for fresh and saltwater aquariums Colour change test: fill plastic cuvette with sample water, add reagent drop by drop until colour changes. Number of drops = level of carbon dioxide content To use: in case of green algae problems, non-growing plants or fish mortality: once a week Healthy aquariums with conditions close to natureThe right water values are dependent on the fish stock and the plants in the aquarium. Even if the water looks clear it can be contaminated. With bad values diseases or algae can appear in the aquarium. To maintain a healthy aquarium with conditions close to nature it is important to check and adapt the water values regularly. For each water analysis JBL provides water tests in the form of quick tests or colour change tests. These determine a certain value or several values in one go. With these water tests you can recognise algae problems and negative nitrate, nitrite, potassium, magnesium values etc. Why test?Carbon dioxide is the most important plant nutrient. The optimal value lies between 20-25 mg/l. This level is harmless for fish and ensures thriving plant growth.

JBL Tropol - Tropical water conditioner for easier acclimatization of all blackwater fish. Creates a crystal-clear tropical water environment and prevents algae. Promotes fish health thanks to humic substances from peat and tannins from oak bark. Promotes readiness to spawn thanks to active iodine. Facilitates the acclimatization of all blackwater fish (e.g. neon, angelfish, discus etc.). Has a stress-reducing effect. Don't worry - your aquarium water will not turn black or brown when you use JBL Tropol! The humic substances contained only give the water a coloration that is barely visible to the human eye, but which is an excellent prevention against algae growth. Only with a strong overdose is a clear brown coloration of the water visible to the naked eye.
