Troubleshooting
Five-angled Pipewort problems — and how to fix them
Five-angled Pipewort (Eriocaulon quinquangulare) 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 melt on introduction
Common when transitioning from emersed or different water parameters. Maintain pristine water chemistry and the plant will recover slowly.
Stunted growth
Usually due to hard or alkaline water. Soften with RO water blending and check active substrate pH.
Yellowing or bleaching leaves
Iron or manganese deficiency; increase chelated iron dosing and confirm micronutrient balance.
Algae on leaves
Slow-growing rosettes are prone to algae in low-flow areas. Increase circulation and add fast-growing stem plants to compete for nutrients.
Rotting crown
Do not plant the growing point below substrate level. Keep only roots buried; the rosette crown should be at or just above substrate surface.
