MicroBacter Start XLF
Starting a new tank? Had a filter crash? Cleaned a little too hard? MicroBacter Start XLF is one of those products that is great to have around just in case.
This is a super concentrated live nitrifying bacteria that helps get your biological filtration going and helps bring ammonia and nitrite down fast. It is made for cycling new freshwater aquariums, but it is also really helpful after medications, major cleanings, overcrowding, or anything else that may have messed with the good bacteria in your filter.
It is 15x strength, so a little goes a long way. Brightwell says most tanks can cycle in around 5-7 days when used as directed, but always test your water before assuming the system is stable.

Used this after a heavy cleaning and noticed ammonia levels dropping within a few days. The instructions were clear and it worked well for my 20-gallon tank. Would recommend for new setups or after filter issues.
Nathan Smith –
Helped stabilize my tank after a medication treatment. Ammonia spiked initially, but after adding the bacteria, levels stabilized quickly. A reliable product for emergencies.

Great for cycling a new tank. Added it on day 3 and by day 5, nitrite was almost gone. The bacteria seemed to establish fast and the tank has been stable since.
