This highly effective tool helps to remove or extract waste before it has a chance to break down and pollute your aquarium, decreases the build-up of harmful aquarium toxins, extends the intervals between water changes and regular maintenance, lightens the load on your filter, and saves you money by reducing the amount of additives required for water maintenance. Also picks up plant debris, excess food, and other large waste particles.
