The manufacturer informs:

Marine aquarium cleaner designed to clean live rock surfaces, decorations and aquarium plates.

• A complex polymeric product for systematic cleaning, specifically formulated to clean the surfaces of live rock and decorations in the aquarium.
  
• Removal gentle removal of build-up, debris and unwanted coatings, facilitating their removal by scraping and vacuuming
  
• Flocculation of particulate matter from residual food, debris and precipitation
  
• Prevents particles from settling and accumulating on rocks
  

It is advisable to discontinue the use of activated charcoal while taking this product as activated charcoal can reduce its efficacy.
Once the aquarium has achieved the desired appearance, activated carbon can be put back into the filtration system if desired. Due to the speed at which filters collect particulate material, it may be necessary to clean the mechanical sponges of the filter every other day when dosing this product.

Razor Marine acts slowly and may require several applications to achieve the desired effect.
When used as directed, it is safe for fish, hard and soft corals and other invertebrates, as well as for most macroalgae; however, all aquarium inhabitants must be observed closely during the product's dosing cycle to detect any signs of stress (closing and non-reopening of polyps, irregular behaviour, etc.). If there are signs of stress or if the macro-algae are adversely affected, reduce or discontinue feeding if necessary. If symptoms persist, carry out a partial water change and add carbon.
