Aquatic plant weights, set of 20 with cotton, for Hornwort, Cabomba, etc. Aquatic plant cultivation, weights, cotton.

This is a set of 20 filter media pieces for aquatic plant weights and cotton. The filter media is harmless and can also be used to improve water quality. You can thread 1-3 Anacharis or about 5 Hornwort stems through the holes and bury them to anchor the plants. The filter media provides an ideal habitat for beneficial bacteria, breaking down harmful ammonia and nitrite produced by leftover food and fish waste.
The rings measure approximately 1.5 cm in height and 1.5 cm in width, though sizes may vary slightly due to manufacturing. Please refer to the images for consideration.
The cotton makes it easy to set up your aquatic plants.
Wrap the roots of your aquatic plants and insert them into the weights.
