### ⭐⭐⭐⭐⭐ Cyano Solution!
*by D***L on November 20, 2025*

### ⭐⭐⭐⭐⭐ Works really fast and really well! I recommend it as long as you follow instructions
*by Y***I on June 16, 2020*

I have been battling sheets of slimy black organic matter that I thought was algae for years in my 15 gallon column. The bioload is low 3 black skirted tetras, 3 neons and 1 betta and I have been losing bottom feeders like Cory Cats and Snails over and over. I have cleaned the tank, I have changed water, used anti-algae chemicals to no avail. I was doing research on the internet and came to be suspicious that it may not be algae but instead cyanobacteria. After doing further research I found links to this product. I thought at this point, I have nothing to lose and sprung for it. After the product arrived, I was reading the instructions and it said "make sure to increase oxygenation in tank". I was not sure what this meant so I called the number on the box and...."GOT A LIVE PERSON!". He told me that it would be a good idea to get another pump and large airstone and circulate more air into the water as what this product basically does is take the oxygen out of the water. He really knew his stuff and was super friendly. (He recommended I also try some Chemiclean Green once this treatment was done in my filter which I also got and it worked great! Another review) So I rigged up another pump and airstone. Followed the directions based on the size of my tank and put the powder in. Within 20 minutes the sheets of slime were coming off my plants (see pictures) and falling off by 48 hours 90% of the dark stuff was gone. Stuff that I used to have to scrub clean only to come back in a day. I did the recommended water change and so far 3 days later the tank is cleaner than it has been for years (see picture) I am going to probably hit it with another dose in a month (per instructions) and see how it goes. I usually wait a few weeks before giving a review but this stuff worked so fast and so nicely that I had to post. Also the guy I spoke to at Chemi Clean was super nice and very easy to work with. The fact that I got a live person that knew his stuff says volumes about the company. Highly Recommended!!!
