Brightwell Aquatics MicroBacter7 - Bacteria & Water Conditioner for Fish Tank or Aquarium, Populates Biological Filter Media for Saltwater and Freshwater Fish, 500ml

very good --buying it on regular basis

My reef tank was filled with Dinos and recurring Cyanobacteria..... ( they are both forms of bad bacteria ). This product introduce some good bacteria into my tank that effectively ate all the bad bacteria. In short ..... my tank is cleaner and safer to my corals.

I guess it works, I use it as directed and havent had any issues.

Exelente producto

If you know anything about reef tanks you know micro bacteria is your best friend. For the price and the size of the bottle I give it a thumbs up all the way.

Just ad 2 capfuls a day for 3 days then just pour the entire rest on day 4. Wow just 2 days after the rest all test are zero! Cycles the filter fast. Will buy again for monthly servicing. :)

awsome!

It seemed to work well to establish live rock in our reef and fish tank. I use a capful when I change the water or filter just to add a little more bacteria.

One of the best starter bacteria solutions for fresh and saltwater tanks

Works great . Next to nopox this is the best thing to get nitrates and phosphates down. Just make sure to share the bottle like bananas before you use it.
