Twinstar Reactor Algae Inhibitor Replacement Disk

Usually ships in 1-2 business days from our fulfillment center

The Twinstar Reactor is a replacement disk for the Twinstar Algae Inhibitor line. To clean the Twinstar Algae Inhibitor disk, we recommend doing so with the Twinstar Reactor Calcium Cleaner.

The Twinstar Algae Inhibitor effectively inhibits the growth of different strains of algae such as green algae amongst others. This device does so without any negative impact on the aquarium tank ecosystem and is safe for aquatic plants, freshwater fish and shrimp species, and beneficial bacteria. The Twinstar Algae Inhibitor works by eliminating algae spores during the early stages, ultimately preventing it from growing. With the reduction of algae growth, aquatic plant growth is encouraged and aquatic plants are able to remain healthy and compete with algae for excess nutrients in the water column. This further starves algae strains and prevents it from reproducing. It is best to install this device during the initial setup of an aquarium when algae are non-existent.

The results of a comparative test with Glossostigma and Rotala Indica revealed that Glossostigma's growth increased up to 50% and Rotala Indica increased up to 40%.
