Common Diseases

Melt on Transition

Symptoms

Leaves turn translucent, mushy, and dissolve within days of planting; typically occurs when moving from emersed to fully submerged conditions

Treatment

Trim affected leaves; ensure stable water parameters (pH, temperature); provide adequate lighting and nutrients; be patient as new submerged growth emerges

Iron Deficiency (Chlorosis)

Symptoms

New leaves appear pale yellow or white while veins remain green; older leaves may show similar patterns

Treatment

Dose with liquid iron fertilizer (chelated iron); increase lighting if deficient; ensure macronutrient balance to improve iron uptake

Algae Overgrowth on Leaves

Symptoms

Green, brown, or black algae coating leaf surfaces; stunted growth; reduced photosynthesis

Treatment

Reduce lighting duration to 8-10 hours daily; increase water changes; add algae-eating fauna (Amano Shrimp, Otocinclus); improve water flow to prevent stagnant zones

Nutrient Deficiency (Macronutrient)

Symptoms

Stunted growth; yellowing of older leaves; weak runner development; pale coloration

Treatment

Dose with all-in-one liquid fertilizer or macronutrient supplement; ensure substrate contains nutrients; increase water change frequency to replenish nutrients
