Description

Brightwell Aquatics MicroBacter Start XLM is a professional-grade, super-concentrated live bacteria suspension designed for marine and brackish aquariums. Ideal for new tank setups, this 15X formula rapidly jumpstarts the nitrogen cycle by quickly reducing ammonia and nitrite through natural biological processes. Whether you’re cycling a tank, recovering from a filtration crash, or introducing new livestock, MicroBacter Start XLM helps establish a strong and stable biofilter in as little as 7 days under optimal conditions.

This product contains highly selective strains of live nitrifying organisms and specialized enzymes that target nitrogen-based waste. It is especially beneficial in high-bio-load systems, aquariums undergoing maintenance, or during emergency ammonia spikes. MicroBacter Start XLM also helps avoid common pitfalls like “New Tank Syndrome” by establishing the right biological foundation from day one.|

Unlike other products, it is designed to work alongside Brightwell Erase-Cl for ammonia detoxification, and pairs well with QuikCycl for fishless cycling. For ongoing stability, users can transition to MicroBacter Clean or MicroBacter7 after initial cycling. Use MicroBacter Start XLM and see clearer water, healthier fish, and a faster, stronger biofilter.
