Cryptocoryne nurii problems — and how to fix them
Cryptocoryne nurii (Cryptocoryne nurii) 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.
Crypt melt
Sudden leaf collapse and dissolving after disturbance, transplanting or parameter swings; keep the rhizome in place and conditions stable and it usually regrows from the roots.
Algae on leaves
Slow leaf turnover lets algae accumulate under bright light or excess nutrients; lower light, improve flow, and trim affected leaves.
Stunted, pale growth
Poor root nutrition or wrong water chemistry; add root tabs and aim for soft, slightly acidic water rather than hard, alkaline conditions.
Failure to adapt emersed/submersed
Leaf form changes when switching between underwater and emersed culture; expect a die-back-and-reshoot transition and don't disturb the rhizome.
