Brightwell Aquatics MicroBacter7 Complete Bioculture for Fish Tank or Aquarium - Populates Biological Filter Media for Saltwater and Freshwater Fish - Aquarium Water Treatments, 5.28 GAL

I haven't had brown algae like I was having before in my aquarium. Highly recommend.

My tank wasnt settling right but just after 3 days of dosing my water was crystal clear and coral looked happy, ill never not use this in any of tanks from here on out

Small dose and water was totally clear the next day

I used this while I was having high nitrates/nitrites. It turned out that instead a pond plant was dying. So once I removed that the parameters stabalized.

Wouldn’t buy again.

As advertised

I can’t thank you enough for making such a great product. I had a huge nitrate problem and fish were dying daily. I was trying everything I could to help them, doing drastic water changes every other day, using filter additives and other products but nothing seemed to help and they kept dying. I could literally tell a difference within one day of using it. The water became a bit clearer and the fish seemed to be in less distress. But by the second day of dosing my neon tetras, who had been gasping for breath and swimming sideways, were swimming normally again!!! I had lost most of the school over the previous week and thought they were goners for sure but they came back to and it’s day four now and I haven’t lost one more fish! They’re all swimming normally now, the water looks so much clearer and my light is shining very brightly through the tank! I can’t recommend this product enough!! It literally saved my fish’s lives and helped me emotionally as I felt so guilty for losing so many of them. I bought a huge bottle and will keep dosing every day for the next two weeks, and will plan on using it once a week for the rest of my fish keeping days I’m so sold on this product. If they have stock I’m buying as many shares as I can afford LOL

A necessary ingredient in cycling and maintaining my Aquariums biological environment.

Good to have on hand
