Struggling to keep your aquarium plants from floating away? These plant weights are here to help! You get 15 sets, each with a plastic ring and a sponge. Just wrap the plant’s roots in the sponge, slide it into the ring, and place it in your substrate. The weight keeps the plant down while the sponge protects the roots and lets them breathe. No more uprooted plants or messy soil! The rings are white and discreet, about 3.2 x 4.5 cm each, so they don’t take up much space or look ugly. Perfect for beginners or anyone who wants a clean, low-maintenance planted tank. They work with most aquatic plants and won’t harm your fish. Makes aquascaping way easier – finally, your underwater garden stays put!
