Natural Volcanic Stone Aquarium Water Clarifier R40850

EcoBio-Stone safely purifies water, eliminates odors and creates a clear and clean environment for fish and other aquatic life. EcoBio-Stone’s volcanic stone also leaches back the essential calcium and trace minerals, which are normally returned to water with frequent water changes. This dual action creates a perfect ecosystem. Note: if the water in your tank is very acidic please use EcoBio-Stones after acclimating your fish to pH neutral water by doing water changes. The process of building sufficient amounts of bacteria to take care of the conditions in the average tank, normally results in crystal clear water in 2 to 4 weeks, with a sudden clearing of the water.
