TESTIMONIALS

"I started my 3000 liter (792 gallon) recifal aquarium about a year ago. For a few months I couldn't lower the nitrate level (30mg/l), so I stopped planting new Corals in the tank. I did not find any satisfactory product in Europe to solve my problem. On the advice of Nosy Bey in Bordeaux, I tested your product AZ-NO3. The result was exceptional! Five weeks after, the nitrate level in the aquarium is close to zero. The Corals are doing very well! I am attaching some photos of the tank and thank you for the effectiveness of your product"

- Olivier D., France

"This product works as advertised. I have a 110 gallon mixed reef nearly 7 years mature and have utilized this product twice. In both cases, the product worked fantastically without any loss of life, cloudy water or any detriments at all."

- Sierra117

"Great product, works as described. Reduced nitrates from 20 to 5ppm in one week! I follow instructions on the bottle, for my tank 350L/92gal. Didn't get cloudy water at all."

- Fadi Al-Sorakjy

"Best Nitrate Eliminator! Love this product. Its the best / easiest way to keep nitrates under control."
