Ask Finn

Rotala rotundifolia is a classic stem plant for the background and upper midground of aquascapes, producing pink to reddish tones under high light and elevated CO2. Regular pruning encourages bushy side-shoot growth. Under low light the stems grow leggy and remain green.

Common Diseases

Nutrient Deficiency (Nitrogen/Iron)

Symptoms

Yellowing leaves, stunted growth, pale coloration despite adequate light

Treatment

Increase fertilizer dosing; use all-in-one liquid fertilizers or add macronutrient supplements; ensure CO2 levels are adequate

Algae Overgrowth (Green Spot/Hair Algae)

Symptoms

Green spots on leaves, hair-like algae coating stems, reduced plant vigor

Treatment

Improve water circulation, reduce photoperiod to 8-10 hours daily, increase CO2, add algae-eating shrimp or fish, perform regular water changes

Melting (Tissue Degradation)

Symptoms

Leaves become translucent, stems soften and decay, plant appears to dissolve

Treatment

Improve water quality with frequent water changes, ensure stable temperature (22-28°C), increase CO2 and light gradually, remove dead tissue promptly

Calcium/Magnesium Deficiency

Symptoms

Distorted new growth, weak stems, poor coloration development

Treatment

Add comprehensive fertilizer containing calcium and magnesium; test water hardness and adjust if below 2 dGH
