Razor Marine - 125 ml

Brightwell Aquatics Razor Marine is a systemic cleaning polymer formulated for marine and reef aquariums. It works gradually on live rock, aquarium walls, and decorations by loosening unwanted accumulations, debris, and surface coatings so they can be removed more easily through scraping, vacuuming, protein skimming, and mechanical filtration.

The formula also flocculates suspended particles from leftover food, detritus, and precipitation. This gathers fine particulate matter into larger particles that can be captured more effectively by the aquarium’s filtration system. Razor Marine also helps discourage particles from settling and accumulating on rock surfaces.

Razor Marine is a slow-acting maintenance product and may require multiple applications to achieve the desired result. It is not a replacement for appropriate feeding practices, protein skimming, mechanical filtration, regular aquarium maintenance, or proper water parameters.

When used as directed, the manufacturer states that Razor Marine is safe for marine fish, hard and soft corals, other invertebrates, and most macroalgae. Because aquarium conditions and animal sensitivity vary, livestock should be observed closely throughout treatment.

• Systemically cleans live rock, aquarium decorations, and tank walls
• Gently loosens unwanted deposits, debris, and surface coatings
• Makes scraping and vacuuming accumulated material easier
• Flocculates suspended particles for more effective mechanical removal
• Helps prevent particulate matter from settling and accumulating on rocks
• Supports clearer-looking aquarium water and cleaner surfaces
• May help aquarium glass remain cleaner for longer
• Suitable for ongoing marine and reef aquarium maintenance
• Can be used with Brightwell Aquatics MicrōBacterCLEAN when properly spaced

Shake well before each use.

Add Razor Marine to a high-flow area of the main aquarium. The following amounts are for every 50 US gallons (190 liters) of actual aquarium water volume:

Day 1: Add 2.5 mL
Day 2: Add 5 mL
Day 3: Add 7.5 mL
Day 4: Add 10 mL
Day 5: Add 12.5 mL
Day 6: Add 15 mL

Maintenance Dose

After completing the initial treatment, add 7.5 mL per 50 US gallons every other day or as needed.

Adjust each dose proportionally to the aquarium’s actual water volume after accounting for displacement from rock, sand, and equipment.

The cap supplied with the 125 mL bottle holds 5 mL. Measuring with a graduated dosing syringe may provide more precise doses, particularly for smaller aquariums.

Remove activated carbon during treatment because it can reduce the product’s effectiveness. Activated carbon may be returned to the filtration system once treatment is complete.

Mechanical filtration may collect particulate material more quickly during treatment. Inspect filter pads, filter floss, socks, and other mechanical media frequently and clean or replace them as needed. The manufacturer notes that cleaning may be required every other day.

If using MicrōBacterCLEAN during the same treatment period, add MicrōBacterCLEAN first and wait several hours before adding Razor Marine.

• One 125 mL bottle of Brightwell Aquatics Razor Marine
• 5 mL measuring cap

• Keep out of reach of children.
• Not for human consumption.
• Use only as directed in marine aquariums.
• Shake the bottle thoroughly before each use.
• Observe fish, corals, invertebrates, and macroalgae closely during treatment.
• Signs of stress may include corals closing and failing to reopen or unusual animal behavior.
• If livestock stress occurs or macroalgae are negatively affected, reduce the dose or discontinue use.
• If symptoms persist, perform a partial water change and add fresh activated carbon.
• Suspend activated carbon use during treatment because it may reduce the product’s effectiveness.
• Store securely with the cap tightly closed.

The Aquarium Does Not Look Cleaner Immediately

Razor Marine is intentionally slow acting and may require multiple applications. Complete the manufacturer’s six-day dosing schedule while maintaining effective protein skimming and mechanical filtration.

Loose Debris Is Accumulating in Filter Media

This is expected as Razor Marine loosens deposits and flocculates suspended particles. Inspect mechanical filters frequently. Filter pads, floss, socks, and other media may require cleaning or replacement every other day during treatment.

The Product Does Not Appear Effective

Confirm that the bottle was shaken well, doses were calculated using actual aquarium water volume, and the product was added to a high-flow area. Remove activated carbon during treatment because carbon may reduce the formula’s effectiveness.

Corals Close or Livestock Behaves Unusually

Reduce or discontinue dosing and observe the aquarium carefully. If symptoms persist, perform a partial water change and add fresh activated carbon.

Macroalgae Appears Negatively Affected

Reduce or stop treatment. If the condition continues, perform a partial water change and use fresh activated carbon.

Deposits Remain Attached to Rocks or Glass

Razor Marine loosens unwanted accumulations but does not eliminate the need for physical removal. Use an appropriate aquarium scraper, siphon, or vacuum to remove loosened material.

Water Becomes Cloudy or Contains More Suspended Material

The product’s flocculating action can gather particulate matter for filtration. Confirm that mechanical filtration and protein skimming are operating effectively, and clean collected material from the filtration system.

Q: What does Brightwell Razor Marine do?
A: It gradually loosens deposits, debris, and coatings from live rock, decorations, and aquarium walls. It also flocculates suspended particles so they can be captured more easily by mechanical filtration and protein skimming.

Q: Is Razor Marine an algae treatment?
A: The manufacturer describes it as a systemic aquarium surface cleaner, not an algaecide or medication. It supports the physical removal of unwanted accumulations but does not replace nutrient control and regular maintenance.

Q: Is Razor Marine reef safe?
A: According to Brightwell Aquatics, it is safe for marine fish, hard and soft corals, other invertebrates, and most macroalgae when used as directed. Livestock should still be monitored closely during treatment.

Q: How much Razor Marine should I use?
A: The manufacturer provides a gradually increasing six-day dosing schedule based on every 50 US gallons of aquarium water. After the initial treatment, the maintenance dose is 7.5 mL per 50 gallons every other day or as needed.

Q: Should Razor Marine be shaken before use?
A: Yes. Shake the bottle thoroughly before every dose.

Q: Where should I add Razor Marine?
A: Add it directly to a high-flow area of the main aquarium for effective distribution.

Q: Should I remove activated carbon?
A: Yes. Activated carbon should be suspended during treatment because it can reduce the product’s effectiveness. Carbon may be returned to the system after treatment is complete.

Q: Do I need to clean my filter media more frequently?
A: Possibly. As the product loosens and flocculates material, mechanical filtration can collect debris faster. Brightwell notes that filter pads and other mechanical media may require cleaning every other day.

Q: How quickly does Razor Marine work?
A: Razor Marine is slow acting and may require multiple applications. Results depend on aquarium conditions, the type of accumulation, filtration, and routine physical cleaning.

Q: Can Razor Marine be used with MicrōBacterCLEAN?
A: Yes. Brightwell states that the two products can work synergistically. Add MicrōBacterCLEAN first and wait several hours before adding Razor Marine.

Q: Does Razor Marine replace scraping and vacuuming?
A: No. It loosens unwanted buildup so that scraping, siphoning, and vacuuming can be performed more easily and effectively.

Q: What should I do if my livestock shows stress?
A: Reduce or discontinue treatment. If symptoms persist, perform a partial water change and add fresh activated carbon.
