Aquarium Stone for Natural Water Clarification and Odor Removal Featuring Beneficial Bacteria (Medium)

EcoBio-Stones are volcanic rock and cement containing 100% pure beneficial bacteria spores, which effectively clarify cloudy water in aquariums, reducing maintenance. Simply rinse off the EcoBio-Stone, soak overnight and place in aquarium. Using nature's system of purifying water, EcoBio-Stone's beneficial bacteria break down organic waste into ammonia, then into nitrites and then into nitrates, which are processed by vegetation or by anaerobic bacteria changing the nitrates into nitrogen gas, which dissipate into the air. 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. 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.

• ALL-NATURAL TANK CLEANLINESS SOLUTION - The Eco-Bio Stone is a volcanic rock containing beneficial bacteria colonies, which are dispersed about every 30 minutes. Clarifies cloudy water over the lifetime of the stone, up to two years.
• AQUARIUM BIOLOGY WORKS FOR YOU - Speeds up nitrogen cycle, with 100% pure bacteria in spores which germinate in early, middle and late stages, only germinating in the presence of organic waste.
• SLOW AND SAFE EFFECTS - Takes approximately 2 - 6 weeks for results under normal conditions, with no need to add liquid or powder bacteria.
• PAINLESS AND HEALTHY - Safe for all fish, reptiles, amphibians and other aquatic life, and minimizes aquarium maintenance by significantly reducing the need to change water and vacuum gravel.
• RIGHT SIZE FOR RIGHT HOME - Simple to use, no mess aquarium care in fresh or salt water. Quickly establishes nitrifying bacteria in new aquariums reducing length of "new tank syndrome". Medium size treats tanks from 15 to 40 gallons.
