Brightwell Aquatics MicroBacter Start XLM - Concentrated Freshwater Nitrifying Bacteria - Quick Start Fish Tank Starter, Lift Microbe Levels & Water Filtering - Aquarium Water Treatments, 33.8 fl oz

Great to help set up aquarium. Help speed up the process of the new start tank.

If you want to create a New Reef tank in Hurry it's one of the Best Bacteria for Cycle in Tank in 1-2 days. I recorded the results every 2 hours and it's amazing that in first 2 hours it's starts the Ammonia up and down by 4-5 hours and N02 becomes high and down 7-9 hours and N03 takes time little bit more like 22-30 hours. but 38-40 hours its everything in low and as per reef condition. But have to use Bio Media like Live Rock or Carabsea Sand. For my Tank I used CarabSea Life Rock 20 LBS, Carabsea Life Sand (White and Purple) with Reef Sea Reef Salt-Blue one (not Red sea Coral Pro). I don't Turn on the light more than 6 hours in first 2 days and in Day three i Added two SPS and 3 LSP and it's Perfect. PH-8.2, Alkalinity - 9 and Salinity 1.35 now my tank is running perfectly and after 2 days I turn on Light and Protein Skimmer. Money worth with this bacteria

I have been a Brightwell user fro many years, but this product stands out in their lineup. I have used this to start 5 aquariums now, including 2 systems over 800 total gallons. It cycles the tank quickly and gets it safe for fish. I do not follow the instructions to add fish to cycle. I use an ammonia source, such as Fitz Ammonium Chloride to kickstart the cycle.

This did nothing to accelerate the nitrogen cycle in my new tank. My opinion is that it’s a sham. Two weeks in and I still have zero nitrates. I should have seen some increase by now.

I’ve been cycling my tank and have added about 5 of these bottles. Took two months to drop ammonia to 0 and still have no nitrates . I would not recommend at all. Try another brand
