Troubleshooting
Rotala wallichii problems — and how to fix them
Rotala wallichii (Rotala wallichii) 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.
Melting after planting
Sensitive to transition shock and unstable water. Keep parameters rock-steady after planting and allow new submerged growth to establish before judging health.
Sparse, leggy whorls
Too little light produces thin, stretched stems. Increase PAR and confirm CO2 is adequate for tight, full whorls.
Tip stunting in hard water
Hard or alkaline water and micronutrient gaps stunt growth. Soften water if needed, hold pH 6.0-7.0, and dose trace elements consistently.
Pale colour
Lacks its pink-red tones without high light and iron. Boost light and iron dosing while keeping nitrate from running high.
