About this product
Dose this aquarium water treatment into a new tank to start a nitrogen cycle, or into an existing one that has been knocked back; the brand states cycling in 7 days in most cases. The bottle holds 125 ml of liquid concentrate at 15x strength. It is made for marine and brackish aquariums.
What the live culture does in a marine or brackish tank
MicroBacter Start XLM carries live, non-pathogenic microbes, and the manufacturer describes the formula as concentrated to 15x strength. The culture is supplied in a proprietary base that the brand gives as the reason for its longevity.
- The manufacturer states that the product establishes a new nitrogen cycle or boosts an impaired one, and that it accelerates the rate at which beneficial nitrifying bacteria colonize.
- According to the brand, it breaks down nitrogenous waste and eliminates ammonia and nitrite spikes.
- The brand lists crowded tanks, tanks with high population densities and the addition of new fish among the situations it is intended for.
- The manufacturer states that the product prevents "New Tank Syndrome" and accelerates the re-establishment of fish tank bacteria after upsets.
When the brand says to add it
The manufacturer names emergencies and the period after a course of medication as occasions for re-establishing a damaged bacteria bed. It also gives cleaning of rocks and surfaces, or the end of medication use, as the best time to dose.
Kept at room temperature, the bottle stays usable for more than a year, and it works with many kinds of sand and rock substrate.
Does it suit your tank?
The stated fit is marine and brackish aquariums. A freshwater tank falls outside that description, and so does any tank the brand does not list here. Check that your setup is a saltwater or brackish system before you buy.
The culture is meant for tanks that are being cycled, are heavily stocked, or have just received new fish. Compatibility with sand and rock substrates is stated; a substrate the brand does not cover is outside that statement.
