APIs algae eater wafers have been developed not only to nutritionally support your fish, but also to improve their overall aquarium environment. These wafers are made with a rich blend of algae plus Omega-3 fatty acids to help promote healthy growth and development, plus alfalfa to promote a good digestive system. They also contain a unique, nutritionally enhanced protein to ensure easy uptake of nutrients, for maximum absorption – which leads to less waste on your fishs behalf.
