Full Details

Chemi Clean is by far our most favorite product for combating Cyanobacteria in saltwater aquarium. The extremely safe formula will not harm the livestock in the tank, while effectively eliminating any red slime. Its fast acting formula will finish the job within 48 hours, by oxidizing trapped organic sludge and promoting an ideal enzyme balance.


  • Available in dry powder or liquid
  • Compatible with Fresh and Saltwater
  • Completely safe for all fish, invertebrates, and coral
  • Will not harm nitrifying bacteria


For the best results, turn off or remove any carbon filtration source, UV sterilizers, protein skimmers, and ozone before administering Chemi Clean to the aquarium. After treatment is complete perform a 20% water change, after that point any carbon filtration, UV, protein skimmers*, or ozone may be turned back on.


*It is very common for protein skimmers to over skim for a period of time after treatment is complete and is completely normal. We suggest monitoring the skimmer cup and removing any collected skimate from the aquarium and not letting it drain back into the water column. If your skimmer is overflowing too fast, you can try restricting the air supply feeding the skimmer and that will decrease the amount of bubbles being formed or simply physically raising the skimmer will allow a faster drain and a dryer skimmate to be produced. Replace any removed water with freshly mixed saltwater.


Chemi Clean will remove and clean stains from red, black, blue-green, and methane producing cyanobacteria in marine aquariums.


Note: When using Chemi Clean it is very important to monitor oxygen and pH levels within the aquarium. We suggest pointing a powerhead or air stone at the surface of the aquarium to maximize gas exchange. Failure to do so can cause low oxygen levels in the aquarium.

    It didn't completely remove the cyano in the tank in one dose, but it definitely knocked it back. Using the dosing recommendations on the instruction sheet, I saw no adverse effect in a sps dominant tank.
