Common Diseases

Nutrient Deficiency (Iron/Macronutrients)

Symptoms

Yellowing or pale leaves, stunted growth, loss of vibrant green coloration

Treatment

Increase fertilizer dosing (all-in-one or macronutrient supplements); ensure CO2 is adequate; test water parameters and adjust accordingly

Algae Overgrowth (Black Beard/Thread Algae)

Symptoms

Dark filamentous or brush-like algae coating plant leaves and runners

Treatment

Reduce lighting duration to 8-10 hours daily; increase water changes; introduce algae-eating shrimp or fish; manually remove affected portions; ensure adequate CO2 and nutrient balance

Melting/Tissue Decay

Symptoms

Leaves becoming translucent, mushy, or dissolving; browning at leaf edges

Treatment

Improve water quality with frequent partial water changes; ensure adequate CO2 and lighting; remove severely affected leaves; check for ammonia or nitrite spikes

Slow/Stunted Growth

Symptoms

Minimal new leaf production, small rosettes, lack of runner development

Treatment

Increase CO2 injection to 20-30 ppm; boost fertilizer dosing; ensure medium-high lighting (8-10 hours daily); verify substrate contains nutrients; maintain cooler water temperature (23-25°C)
