Peoples Choice - Other Highly Rated Ammonia Aquarium Water Treatments

2. Seachem Stability Fish Tank Stabilizer - for Freshwater and Marine Aquariums 500 ml

User Ratings: 87 2

Seachem First Impressions

"Wow my tank is so clear."

You need a source of ammonia to feed the bacteria which Dr. You need to buy an eye dropper for this. I have used this consistently since cycling my small sized fresh-water tank. This product is exactly what it says it is. If you're treating injured fins or introducing new fish, this is for you. I use mine for my beta fish in a 2 gallon tank and need less than a half a cap full. Now our fish have grown and we've added live plants.

• Seachem Stability Fish Tank Stabilizer - for Freshwater and Marine Aquariums 500 ml
• TANK STABILIZATION: Seachem Stability will rapidly and safely establish the aquarium biofilter in freshwater and marine systems, thereby preventing the #1 cause of fish death: "new tank syndrome".
• TREATMENT: Stability is formulated specifically for the aquarium and contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, nitrite, and nitrate.
• BACTERIA GROWTH: The necessary conditions for the growth of Stability's bacteria strains encompass a very broad range. When other bacteria begin to die off (usually from high organic loads caused by the unknown death of an organism), Stability simply becomes more effective.
• USE: Shake Seachem Stability well before use and turn off UV/ozone filter. Use 1 capful (5 mL) for each 40 L (10 US gallons) on the first day with a new aquarium. Then use 1 capful for each 80 L (20 US gallons) daily for 7 days. Fish and other aquatic species may be introduced at any time as long as dosage is maintained for 7 days.
• SAFE: The bacteria employed by Stability are non-sulfur fixing and will not produce toxic hydrogen sulfide. Stability is completely harmless to all aquatic organisms as well as aquatic plants, thus there is no danger of overuse.

"It was a viscous cycle."

From their own colon or a hole in the ground. Sure enough they are back to their healthy coloration and didn't end up dying on me. I read another review for this product saying they were using API for this purpose. Do not gravel vac or disturb the substrate. I like API products and this is no different. Initially this was used as a sample packet came with our aquarium. I'm sold on this, I've tried SO MANY and wow.
