Carib Sea Instant Aquarium Rio Grande

CaribSea's Instant Aquarium™ takes the guess work out of starting a new tank. This line of substrates offers a variety of gravels and sands water-packed with living, water-purifying bacteria, state of the art clarifier, and a complete water conditioner. Instant Aquarium™ immediately begins the cycling process, eliminating "new tank syndrome", and discouraging nuisance algaes. It detoxifies metals, eliminates ammonia, neutralizes chlorine and chloramines, and provides a protective slime coat for stressed fish. Also reduces nitrates and nitrites.
