This is great for any discus aquarist trying to achieve a lower pH for discus. It is better than reverse osmosis water. Day. I currently have more than enough in my 75 gallon planted tank. I change the water weekly and barely scratch the surface. I keep my pH around 6.4 and it stays stable until I do a water change. good product.
