Pflegehinweise
Azolla filiculoides is very easy to maintain. It prefers moderate to strong light but tolerates low light. Ideal temperature is between 15 and 30 °C. pH 5.0–8.0 and low to medium hardness are suitable. No added CO2 is needed. Liquid fertilization can boost growth. Avoid strong water flow that scatters the plants. Regular thinning is required to prevent overgrowth. Compatible with most fish and shrimp.
