API® AlgaeFix controls the main and most persistent types of algae in freshwater aquariums, and does so without causing harm to your fish or plants. You can use AlgaeFix as part of your aquarium maintenance routine, or to directly treat and control algae. Weekly doses of AlgaeFix will control algal growth and reduce aquarium maintenance over time. Do not use with freshwater crustaceans, including shrimp, crabs, and lobsters.

Jerry Roob –
it works well. just follow instructions
Dr. Dedrick Brekke Jr. –
I have 2 tanks I have used this on. A 10gal and a 5gal today is day 3 of the first treatment and the green algae is already brown and the water is so much clearer. The measuring device only has a 5ml and 10ml dose level so I used a medicine syringe for the low doses. 10 gallon tank requires 1ml and the syringe worked perfect.
