Troubleshooting
Dwarf Water Clover problems — and how to fix them
Dwarf Water Clover (Marsilea minuta) 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.
Algae overgrowth
Slow-growing carpet leaves are quickly smothered by green spot or thread algae, especially during the initial establishment phase. Maintain consistent CO2 (in aquaria), reduce photoperiod to 8–9 hours, and introduce algae-eating invertebrates such as Amano shrimp.
Etiolation in low light
Insufficient light causes stems to stretch upward rather than forming a carpet, producing tall, leggy plants. Increase light intensity or duration; trim elongated stems and replant cuttings into the substrate to encourage compact regrowth.
Uprooting by fish or flow
The delicate rhizomes are easily dislodged by digging fish (cichlids, goldfish) or strong water currents. Plant in small clusters, anchor with fine mesh or plant weights initially, and position away from filter outlets.
