Aquatopia pH Up Powder 1kg - Premium Water pH Balancer for Pools, Spas & Hydroponics | Fast-Acting pH Increaser for Crystal Clear Water

This product is used for raising the pH of aquarium water from acidic to neutral or neutral to alkaline. Most fish can adapt to subtle changes in pH but extreme changes should be avoided as big variations in pH can be harmful to fish. All pH changes should be made gradually (over several days) to allow fish to adjust to the change.
