Ask Finn

Spectacular Australian Ottelia with large, heavily ruffled leaves. One of the most dramatic aquatic plants. Very challenging to keep long-term.

Common Diseases

Algae Overgrowth

Symptoms

Green, brown, or black algae coating leaves; reduced light penetration; plant growth stunted

Treatment

Increase water changes, reduce lighting duration, add algae-eating fish (Otocinclus), manually remove algae, ensure adequate CO2 and nutrient balance

Nutrient Deficiency

Symptoms

Yellowing or pale leaves, stunted growth, leaf deformation, loss of ruffled appearance

Treatment

Dose comprehensive liquid fertilizers containing macronutrients and micronutrients; test water parameters; consider substrate fertilization or root tabs

Melting (Tissue Decay)

Symptoms

Leaves become translucent, mushy, and disintegrate; rapid deterioration after planting

Treatment

Improve water quality and stability; increase CO2 levels; ensure adequate lighting; perform frequent water changes; remove affected leaves; acclimate plant slowly to new conditions

CO2 Deficiency

Symptoms

Slow growth, pale coloration, leaf curling, loss of leaf ruffling and dramatic appearance

Treatment

Install pressurized CO2 system; maintain 20-30 ppm CO2; use drop checker to monitor levels; ensure proper diffusion and circulation
