Troubleshooting
Madagascar Lace Plant problems — and how to fix them
Madagascar Lace Plant (Aponogeton madagascariensis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaf decay and disintegration
The most common problem. Caused by water temperatures above 24°C, high lighting, excessive detritus accumulation, or bacterial attack. Maintain cool (18–23°C) water, low light, and weekly water changes. Remove decaying leaves promptly to prevent bacterial spread.
Bulb rotting
Often caused by burying the bulb too deep, poor water circulation around the crown, or warm stagnant water. The bulb should be half-exposed above the substrate. Ensure gentle water movement at substrate level.
Algae on leaf lattice
Green or brown algae colonizing the intricate lattice gaps kills the leaf rapidly. Caused by excessive light or high nutrients. Reduce photoperiod, add floating plants to shade the tank, and introduce algae-grazing invertebrates (Amano shrimp, nerite snails) cautiously.
