Review on 🐠 Fritz Aquatics Water Clarifier: Optimal Solution for Freshwater and Saltwater Aquariums by Wendy Johnson

I used this product and on the 4th use it killed 3 of my neon tetras. I couldn't tell if the water was being cleaned by this product or my other cleaning habits and other products I used with this product. I have read that this product can be toxic depending on your water parameters. All my parameters were normal. Shortly after dosing the prescribed amount, all of my neon tetras were up in the tank gasping for air. I did a big water change and saved the rest of the fish. I threw this product in the trash. Watch out for products that use flocculants. Other brands also killed fish after the review.
