Review: Great product - Been using this for months in my marine tank.
Review: Cleared my red cyano problem overnight! - This product arrived just over 24hrs ago and I am really impressed with it. Its several different strains of helpful, safe bacteria in a bottle. So won't harm fish, coral, sponges, anemones, worms etc or the bacteria in your live rock and filter. After a small water change and quick syphon of the really bad parts of my sand I used this as directed on the bottle (remember to turn protein skimmer off for 4 hours). I did this late at night so went to bed. The following morning I woke up to a pristine tank.. it looked brand new inside! Water looked clearer, fish looked brighter and corals etc looked healthier. I was recommended this by a friend to use alongside Microbacter Clean regularly and their tank is now crystal clean and healthy. So will definitely be using this for the foreseeable..

### ⭐⭐⭐⭐⭐ This really works!!!
*by P***N on 13 August 2021*

This product will help your reef system in more ways then one. I had an issue with cyanobacteria and dino, after over doing carbon source my tank and has suffered double zero phosphate and nitrate. so after lot of research and using different chemicals products that didn't really work, this microbacter7 made a massive difference. I dose this for two week as per the instruction and then 3 day black out. All is back on track with my reef tank again. I will definitely be continuing using this product to maintain the balance of my reef, it made all the difference. I hope this review will help out another reefer.
