Riccia Fluitans

Position and planting

Float at the surface. Thin the growth as needed to maintain light, gas exchange, and access to the water surface.

Can float or be tied to hardscape; strong light and CO₂ help produce dense growth.

Lighting, CO₂ and nutrition

Light: Medium–High. CO₂: Recommended. Difficulty: Moderate.

The library lists added CO₂ as recommended. Stronger lighting and CO₂ require careful, balanced fertilization.

Keeping it healthy

Provide consistent light, suitable nutrition, and routine maintenance. Remove decaying leaves. Watch for algae or melting after transitions, and troubleshoot conditions before making sudden changes.
