Seachem Stability is a scientifically formulated bacterial supplement designed to kick-start the biological filtration in new aquariums and maintain it in established tanks. It introduces a synergistic blend of aerobic, anaerobic, and facultative bacteria that work together to break down organic waste, ammonia, nitrite, and nitrate. This helps to prevent the dreaded “new tank syndrome” and keeps water parameters stable over time. Safe for all aquatic life, Seachem Stability is an essential addition to your aquarium maintenance toolkit, ensuring a healthy and balanced ecosystem with minimal fuss. 250ml container.
