I added duckweed to my shrimp tank and noticed a clear improvement in water quality within a week. The plants spread quickly and covered the surface well, giving my shrimplets a safe place to hide. Easy to maintain and no special equipment needed.

Grew well in low light and helped reduce nitrates. The golf ball size makes it easy to measure and add. My shrimp seem more active now, probably because of the added cover.

Perfect for beginners. No CO2, no special lighting—just drop in and watch it grow. The coverage is excellent and the water stays cleaner than before.
