Seachem Stability 250ml

Seachem Stability is a scientifically formulated biological additive designed to establish and maintain a stable and healthy biofilter in both freshwater and saltwater aquariums. Unlike traditional cycling methods that can take weeks to fully establish a biological filter, Stability offers a faster, safer alternative that prevents the buildup of harmful substances such as ammonia, nitrites, and nitrates, which can be lethal to fish and other aquatic organisms.

At the heart of Seachem Stability is a carefully selected blend of beneficial bacteria. These bacteria work together to break down waste materials in the aquarium, converting harmful ammonia and nitrites into less toxic nitrates. What makes Seachem Stability unique is that it contains species of bacteria that are non-sulfur-fixing, meaning they do not produce toxic hydrogen sulfide, a common problem with other bacterial additives. This ensures that Stability is entirely safe for use in all aquarium types, including those with delicate fish, plants, corals, and invertebrates.

The product is particularly beneficial during the critical initial setup of a new tank, where fish and other aquatic creatures are most vulnerable to “new tank syndrome.” In this phase, ammonia and nitrite levels can spike due to a lack of established bacteria to break them down, often leading to stress or even death for fish. Seachem Stability helps avoid this by rapidly introducing the necessary bacteria to start the nitrogen cycle, ensuring a quick and efficient transition to a stable environment.

Seachem Stability is also highly effective for maintaining an established aquarium’s biofilter during stressful events such as adding new fish, performing large water changes, cleaning the filter, or administering medications that might harm beneficial bacteria populations. In these cases, Stability helps replenish and reinforce the bacterial colonies, ensuring they continue to process waste effectively and keep harmful compounds at bay.
