Brightwell MicroBacter Starter XML 250ml

MicroBacter Start XLM 15X creates a nitrifying biological filter in marine & brackish aquaria of all types and is particularly useful for new startups, resulting in cycling in about 5 to 7 days in most cases.  It quickly removes toxic ammonia and nitrite naturally through non-pathogenic nitrifying bacterial action.  Even though this product is extremely potent, it may be overdosed at up to 5 times the rated dosage during aquarium upsets.  It should be your first choice to remove ammonia during emergencies where the filter has been inadvertently killed or under overcrowding.
