Brightwell Aquatics Razor Marine, Systemic Cleaner, Coral Safe, 2 L. /67.6 fl. oz.

Considerations for Use

It is recommended that activated carbon use be suspended while using this product, as activated carbon can reduce the product’s effectiveness. Once the aquarium has attained the desired appearance, activated carbon can be put back into the filtration system, if desired. Due to the rate at which filters collect particulate material, it may be necessary to clean mechanical filter pads and other media every other day while dosing this product. Simultaneous use with MicroBacterCLEAN will have a very synergistic effect. If using MicroBacterCLEAN, use several hours apart.

Active protein skimming and sensible feeding should be the first steps taken to minimize turbidity and the concentration of dissolved organic materials in any marine aquarium. Water of high clarity that is low in dissolved organic material and possesses the proper parameters is the basis for a healthy aquarium system! 

Razor Marine is slow acting and may require multiple applications to achieve the effect desired by the user. Used as directed, it is safe for marine fishes, hard and soft corals, and other inverts, as well as most macro-algae, however, as all animals are individuals, and water conditions vary in many aquariums, animals should be observed closely during use, for signs of stress (corals closing and not re-opening, erratic behavior etc.). If signs of stress occur, or if macro-algae are affected negatively, reduce or discontinue use as necessary. If symptoms persist, do a partial water change and add carbon.

Brightwell recommends that all makeup water in the aquarium be filtered by reverse osmosis or deionization to prevent adding phosphates and silicates. Brightwell also recommends that you regularly test phosphates and keep them at a level of .02 ppm or less. You can lower phosphates by the use of Extrax Phos, FerroxiPhos-G or Phosphāt-E. The use of grazing snails such as turbo snails and nerites can be very helpful in cleaning the rocks and other surfaces. Use with MicrōBacter7 or MicrōBacterCLEAN will be very beneficial. The use of RedoxIclean prior to use of this product, to clean up high organic levels or tea colored water will also be beneficial.
