This product effectively removes nitrate from your aquarium therefore dramatically improving conditions for both fish and plant. Less nitrates means less algae, better plant growth and healthier fish, all the things we strive for as fish keepers.

How does it do it?

The sponge contains microbes which consume the nutrients that algae need to survive, the algae consequently die through starvation.

Check the nitrate level in you aquarium before application with an appropriate nitrate test kit. Once you have the initial reading, check the nitrate level every few days and once it reaches zero the algae will disappear.
