Eleocharis acicularis problems — and how to fix them
Eleocharis acicularis (Eleocharis acicularis) 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.
Tall, sparse blades instead of carpeting
Too little light or CO2. Increase both so the grass spreads horizontally and stays short.
Slow or patchy spread
Poor substrate nutrition. Add root tabs and dose the water column to fuel runner growth.
Algae in the carpet
Dense low growth traps detritus and algae. Maintain flow, keep nutrients stable and add shrimp/snails as cleanup.
Melting after planting
Emersed-grown plugs often melt before adapting to submerged life. Trim, keep conditions stable, and new submerged blades will emerge.
