    Brightwell Aquatics Razor System Cleaner 125ml / 250ml / 500ml

    Brightwell's Razor Aquarium Cleaner will gently loosen accumulations of unwanted substances, debris and coatings like of some nuisance algae, making their removal much easier.

    It will make the overall cleaning action of the marine aquarium easier and help to keep the aquarium glass longer clean.

    It is recommended not to use activated carbon while using Brightwell Razor, as it can reduce the effectiveness of it.
    Once the aquarium has reached the desired appearance activated carbon can be placed back into the aquarium.

    Brightwell Razor System Cleaner is slow acting and may require multiple applications to achieve the desired effect. 

    Used as directed, it is safe for marine fishes, hard and soft corals, and other inverts, as well as most macroalgae. 
    However, as all animals are individuals, and water conditions will vary in many aquariums, livestock should be closely observed during the use of Brightwell's Razor, for signs of stress (corals closing and not re-opening, erratic behavior etc.).
    If signs of stress occur, or if macroalgae are affected negatively, reduce or discontinue use as necessary.
    If symptoms persist, do a partial water change and add carbon.


    1. Shake well before using
    2. Add solution into a high flow area of the aquarium
    3. Add for every 190 l marine aquarium water
    • Day 1: add 2½ ml (½ capful)
    • Day 2: add 5ml (1 capful)
    • Day 3: add 7½ ml (1½ capfuls)
    • Day 4: add 10 ml (2 capfuls)
    • Day 5: add 12½ ml (2½ capfuls)
    • Day 6: add 15 ml (3 capfuls).

    This is absolutely brilliant, I was looking on lots of marine aquarium websites to find a solution to get rid of my green hair algae problem . This stuff literally melted everything off, the green hair algae turned black and started to fall off. Just follow the instructions and you will be amazed how well this works.
