Overview

CyanoEX Liquid™ is a liquid treatment intended for the control of cyanobacteria in freshwater and marine aquariums. It is formulated for precise volume-based dosing and controlled application.

CyanoEX Liquid® is a liquid treatment intended for the control of red, black, and blue-green cyanobacteria (commonly referred to as "red slime"). It may also assist with reduction of organic sludge and improvement of water clarity.

When used as directed, CyanoEX Liquid™ provides targeted reduction of cyanobacterial growth without requiring system shutdown.

Available volumes: 100 mL.

Indications

Use CyanoEX Liquid™ when cyanobacteria forms persistent films or mats on substrate, rockwork, décor, or glass. The tabs below illustrate typical coverage levels and recommended treatment approaches.

Mild cyanobacteria infestation
Mild infestation

Typically presents as a thin film or small localized patches, often limited to low-flow zones.

Recommended dose: 3 mL per 60 L (16 US gal)
Do not exceed the recommended dose.

If cyanobacteria is only present in small areas, consider using the Fog method (spot dosing) for targeted treatment. If it persists, re-dose after 72 hours and address root causes (flow, nutrients, detritus).

Moderate to heavy cyanobacteria infestation
Moderate-heavy infestation

Typically presents as thick mats, broad coverage, or recurrent outbreaks that return after manual removal.

Recommended dose: 3 mL per 60 L (16 US gal)
Maintain strong aeration and circulation during treatment.

Re-dose after 72 hours if required. Correct underlying causes to prevent recurrence.

Fog method spot dosing
Fog method (spot dosing)

The fogging method is a targeted measure to combat cyanobacteria with spot dosing. A liquid substance harmful to cyanobacteria is applied to the affected areas using a disposable syringe. A blunt needle is advisable in case of an infestation in the substrate.

When to use: Mild infestation, localized areas only (small radius).
Targeted application reduces unnecessary exposure of the full system.

How to apply:

  1. Turn off filters or pumps to minimize water flow during application.
  2. Fill a disposable syringe with the required amount of CyanoEX Liquid™.
  3. Apply slowly and precisely onto affected areas (use a blunt needle for substrate if needed).
  4. Allow a few minutes of contact time at the treated location.
  5. Restart technical devices after exposure time.

If necessary, repeat after 72 hours and correct underlying causes (dead spots, detritus buildup, excess nutrients).

Directions
  1. Remove chemical filtration media (such as activated carbon) prior to treatment.
  2. Shake bottle gently before use.
  3. Measure the required amount of CyanoEX Liquid™ using a syringe, pipette, or graduated measuring cup.
  4. Pre-dilute the measured dose in a small volume of aquarium water (recommended for even distribution).
  5. Distribute evenly throughout the aquarium, preferably into an area of active water flow.
  6. Maintain normal circulation and aeration during treatment.

Dosage (recommended): 3 mL per 60 L (16 US gallons)

If necessary, repeat treatment after 72 hours.

FAQ
Will CyanoEX Liquid™ affect biological filtration?

When used as directed, impact on nitrifying bacteria is minimal. Monitor water parameters during treatment.

Can CyanoEX Liquid™ be used in marine aquariums?

Yes. CyanoEX Liquid™ is suitable for both freshwater and marine systems.

Can I exceed the recommended dose?

No. Exceeding the recommended dose may stress aquatic organisms and is not advised.

How quickly will results be visible?

Reduction of cyanobacteria is typically observed within 24–72 hours.

Do I need to turn off equipment?

Maintain normal circulation and aeration. Remove activated carbon and chemical media before dosing.

Safety

For aquarium use only. Do not exceed recommended dosage.

Avoid inhalation of dust. Avoid contact with skin and eyes.

Store tightly closed in a cool, dry location. Keep out of reach of children.
