Tetra SafeStart Aquarium Water Conditioner reduces toxic ammonia and nitrite, adds live bacteria to promote biological filtration and prevents "new tank syndrome" from affecting fish in your tank. It works quickly to allow the immediate addition of fish in new tanks.
This patented mix of proprietary Bio-Spira bacteria is proven to work. Use SafeStart Plus when setting up new tanks, after a water change, when adding fish or after medicating. A single dose of this concentrated solution adds a full filter bed of beneficial bacteria. The formula is shelf-stable and requires no refrigeration.
