Superfish Bactuur Gel contains live filtration and water-purification bacteria.
Ideal for adding 'good' bacteria to your filter so it can become established quicker. This will help the reduction of ammonia and nitrite by converting them into the safe nitrate.
So what's different about this product compared to others?
You literally add it directly to your filter media (like a paste). That means it targets the source (the filter media) as opposed to the water like most filter bacteria products. The live bacteria stay of the filter media which is just what you're looking for. It's so effective, we cannot recommend it more.
Use every time you clean your filter or if you have a nitrite spike.
