How to Use

Note: It is recommended that the pH in your aquarium be greater than 8.0 before you begin to add Red Cyano Rx. This product may reduce the Ph and can affect the Alkalinity in your aquarium, so it is recommended that you monitor your Ph and Alkalinity when dosing Red Cyano Rx. Do not dose in the evenings when lighting is turned off. The best time to start treatment with Red Cyano Rx is in the morning, when lighting first comes on. During the day time Ph trends upward and at night tends to fall. Algae growth in your aquarium will cause your Ph to decrease, and using Red Cyano Rx, while having an overall beneficial effect, warrants caution and monitoring of Ph and Alkalinity. Turn off skimmer and discontinue using activated carbon and ozone.

  • For best results, siphon out as much Red cyanobacteria as possible from your aquarium. 
  • Remove 1 cup of water from your aquarium and mix with 1 level scoop of GreenCyano Rx for every 10 gallons (37.9 liters) of true water volume in your aquarium. 
  • Dissolve thoroughly and pour solution into the aquarium in a high flow area.
  • After 24 hours, perform a 25% water change.
  • If treatment has produced the desired results, resume protein skimming and other filtration, including fresh activated carbon. You may notice increase foam production from your skimmer initially.
  • If cyanobacteria are still visible after 48 hours, perform a 25% water change and repeat dose. It is important to perform a 25% water change after every treatment course.


Warning: This product is not intended for human consumption. Keep out of reach of children. If ingested, contact a physician or poison control center immediately.


Phosphate Rx is an amazingly simple and effective product that has revolutionised the way phosphates are removed from saltwater and freshwater aquariums. When added, the lanthanum-chloride formula rapidly binds to phosphate molecules making them inactive and easily filtered out.


Regular use of Phosphate Rx can increase vitality and growth of your aquarium inhabitants. Phosphate Rx is veterinarian approved and has been used by leading public aquariums, livestock wholesalers, retailers and hobbyists. 



  • Reef safe
  • Fast & effective
  • Pre-mixed liquid solution


How to Use

Note: Do not dose directly in the display tank. Test your aquarium’s phosphate levels prior to use. Do not lower phosphates more than .5ppm in a 24-hour period.

  • Add six drops of Phosphate Rx per 10 gallons of water. This will lower phosphates by approximately .5ppm. It is recommended to maintain phosphate levels below 0.03ppm.
  • For best results, slowly place drops directly into your protein skimmer or into the overflow where the liquid and precipitate can be filtered through a 5 or 10 micron filter sock. Some temporary cloudiness may occur when adding this product. Cloudiness will clear within 24-hours. 
  • For accurate results, wait 24-hours before retesting your phosphate level. Wait ten minutes before dosing other supplements. 
  • Test regularly and treat as necessary.


Caution: Tangs can be sensitive to the recommended dosage of Phosphate Rx, and can be irritated when using this product. Additionally, some wrasses may also be sensitive to this product's use and we recommend spreading out the recommended dosage over 2 or more parts. Do not dose directly in the display tank.
