Common diseases 4Melt on Transition, Iron Deficiency, Algae Overgrowth on Leaves, Calcium/Magnesium Deficiency

Melt on Transition

Symptoms

Leaves turn translucent, mushy, and dissolve; plant collapses within days of introduction

Treatment

Acclimate slowly over 2-3 weeks; ensure stable soft, acidic water (pH 5.5-6.5) before planting; maintain high CO2 and consistent lighting

Iron Deficiency

Symptoms

Yellowing of new growth while veins remain green; stunted leaf development

Treatment

Dose liquid iron fertilizer (chelated) 2-3 times weekly; ensure adequate lighting and CO2 to support nutrient uptake

Algae Overgrowth on Leaves

Symptoms

Green or brown algae coating fine foliage; reduced photosynthesis and plant vigor

Treatment

Increase water column flow; reduce photoperiod to 8 hours; manually remove affected leaves; add algae-eating shrimp; maintain nutrient balance

Calcium/Magnesium Deficiency

Symptoms

Pale, weak new growth; leaves curl or develop necrotic spots; stunted rosette formation

Treatment

Dose comprehensive liquid fertilizer containing calcium and magnesium; perform 30% water changes weekly; test and adjust GH to 2-4 dGH
