This is great for saltwater where we're trying to maintain a PH of 8.2 and buffer calcium for corals. This isn't so good for freshwater. Aragonite sand is also very expensive compared to silica based sand. We suggest you stick with play sand / pool filter type sand (all silica based sand) for any freshwater tank.
