Troubleshooting
Crisped Water Trumpet problems — and how to fix them
Crisped Water Trumpet (Cryptocoryne crispatula) 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 after transplant
Leaves may suddenly yellow and collapse when moved to a new tank. Maintain stable water chemistry, remove melted leaves, and allow the rhizome to regenerate — recovery typically takes 2–4 weeks.
Narrow pale leaves
Insufficient light or iron deficiency produces thin, washed-out foliage. Increase lighting duration or add an iron-enriched aquatic fertiliser.
Slow growth
Low CO2 levels limit growth in planted tanks. Supplemental CO2 injection noticeably accelerates leaf production.
Algae on leaves
Excess light or phosphate imbalance encourages algae colonisation. Adjust light schedule and maintain balanced fertilisation.
Root rot
Anaerobic, compacted substrate causes root die-back. Use a porous substrate and avoid over-planting in a small area.
