Brightwell MicroBacter Start XLM Live Bacteria for Fast Aquarium Cycling (250ml)

$45.00

MicroBacter Start XLM is a professional-grade live bacteria solution formulated to rapidly establish biological filtration in new marine, reef, and brackish aquariums. This highly concentrated 15X formula introduces active nitrifying bacteria that quickly convert toxic ammonia and nitrite into less harmful nitrate, helping to stabilize water conditions during the critical startup phase.

Designed for both new tank setups and emergency use, MicroBacter Start XLM is highly effective in situations where biological filtration has been compromised, such as after heavy cleaning, medication use, overcrowding, or sudden ammonia spikes.

When used correctly, MicroBacter Start XLM can significantly shorten cycling time, often achieving a full cycle in as little as 7 days. It also helps prevent “New Tank Syndrome” by establishing a strong and stable bacterial foundation early in the aquarium’s lifecycle.


Key Features

• Live nitrifying bacteria for rapid aquarium cycling
• Highly concentrated 15X professional formula
• Quickly reduces ammonia and nitrite levels
• Helps prevent “New Tank Syndrome”
• Ideal for new aquariums and emergency recovery
• Supports strong and stable biological filtration
• Suitable for marine, reef, and brackish systems


Instructions

Shake well before use. Add the recommended dosage directly into an area of high water flow.

For new tank cycling, dose according to aquarium volume and monitor ammonia and nitrite levels daily. Continue dosing as needed until both ammonia and nitrite reach zero and nitrate is present.

For emergency use, higher dosing may be applied to rapidly reduce ammonia levels.


Important Notes

Always dechlorinate tap water before use, as chlorine and chloramines will kill beneficial bacteria.
Avoid using UV sterilizers, ozone, or chemical filtration during the cycling process.
Do not combine with other bacterial products during initial cycling.
