Care Guide
Water Conditions
To thrive, Aponogeton crispus requires stable conditions with a temperature range of 72°F to 82°F (22°C to 28°C). The plant prefers slightly acidic to neutral pH levels, ideally between 6.0 and 7.5. A well-maintained filtration system is essential to prevent debris from accumulating on the leaves.
Lighting
Moderate lighting conditions are optimal for the Ruffled Sword Plant. A light intensity of 2 to 3 watts per gallon is recommended, mimicking its natural habitat's dappled sunlight. While it can tolerate lower light levels, inadequate lighting may hinder foliage growth and lead to poor overall health.
Pruning
Regular pruning of old or damaged leaves will promote new growth and maintain the plant’s aesthetic appeal. Remove any yellowing leaves to encourage a robust and healthy plant while controlling overgrowth.
Nutrient Requirements
CO2 and Fertilization
Aponogeton crispus thrives with supplementary CO2, which promotes vigorous growth and helps achieve lush foliage. Implementing a balanced fertilization schedule with liquid fertilizers or root tabs will provide essential nutrients, particularly nitrogen, potassium, and trace elements, which are vital for optimal development.
Light Requirements
In conjunction with CO2 supplementation, maintaining proper lighting as mentioned earlier is crucial. This combination ensures your Ruffled Sword Plant flourishes and enhances your aquascape.
Natural Biomes
