Pharmaceutical Grade Salt for the Modern Aquaria!

Tropic Marin's Pro-Reef is the ideal foundation for any new tank from fish only to a full-blown reef tank. When used as your regular salt mix it will help bring better ionic equilibrium to the tank, stabilizing pH and allowing the proper balance of carbonates to bicarbonates, leading to faster overall coral growth. Designed to meet the strict requirements of reef aquariums, Tropic Marin Pro Reef Salt mix contains optimized levels of calcium and magnesium while keeping the correct pH value and a balance of all 70 trace elements required by corals to grow and thrive. 



  • Incredibly pure; mixes fast & clear
  • Helps stabilize pH
  • Made from pharmaceutical-grade materials
  • Suitable for systems using a calcium reactor
  • Optimizes calcium & magnesium
  • Contains all major and minor elements
  • Perfect for fish only or coral reef aquariums
  • Free of unwanted nitrates or phosphates


Three Sizes Available

  • 100 Gallon Mix (Box)
  • 160 Gallon Mix (Box) *BEST VALUE*
  • 200 Gallon Mix (Bucket)


Parameters (approx)

  • Alkalinity - 7
  • Calcium - 440 ppm
  • Magnesium - 1350 ppm



We suggest starting with 1/2 Cups of Tropic Marin Pro Reef Salt per 1 Gallon of RODI water. For the best results, the water should be circulating and at a temperature of 73-77 °F. Once the water is up to temperature and circulating, slowly adding the appropriate amount of salt will allow it to fully dissolve quickly without creating any concentrated areas where precipitation may occur. 

When you have added almost all of the salt and the mixture is fully dissolved and clear, start measuring the specific gravity with a refractometer or similar instrument. Keep adding small amounts of salt until the specific gravity is the value you desire. The specific gravity of the sea salt solution should range from 1.025 to 1.027 (at 73-77 °F / 23-25 °C) and the pH -value should be in the range of 8.0 – 8.4. If all parameters are correct, the salt water is ready to use.

Note: Always add the salt to the water, never the water to the salt.

Product Questions

How is this salt different than the Classic or Bio Activ salt?
Question by: Jeff Johnson on Dec 26, 2018, 6:21 PM
Thanks for the question!

The Pro Reef salt is a balanced salt mix with levels for Alk closer to natural seawater. This Alk level is a little lower than some reefers aim for, but is intentionally so for balanced and stable parameters for storage and inside the tank.
The Classic salt has elevated Alkalinity, but lower Calcium and Mag for those who desire higher Alk. There also is a balanced ratio of Alk to Calcium with this salt mix, but in reverse of the Pro Reef, in order to help prevent precipitation.
The Bio-Actif salt is just like the Pro Reef, except it is intentionally higher in Alk and also includes carbon dosing compounds for a "dual purpose" type of salt. This is recommended to be mixed up and used as needed due to the elevated levels of Alk/Ca as well as the potential for carbon dosing compounds to break down over longer term storage.

I have been using this salt for 6 months and just noticed it states it includes all trace elements. I have also been using the Triton Other Method to does calc, alk and mag because it has trace elements. Is my tank getting to many trace elements using both?
Question by: Dana on Nov 9, 2019, 8:07 PM
Hey there-

Great question! While the salt contains all major, minor, and trace elements that you would find in the ocean it will not supplement or maintain these trace element levels unless you are performing frequent water changes. The Triton supplements are a great way to replenish these levels as they are consumed by your reef system.

Happy reefing! c:

The stated Alkalinity level at 7.0 is lower than BRS recommends (>8.0), while Calcium and Magnesium levels are in line. For someone using an ionic balanced 2 part, what is the recommended way to raise the Alk level?
Question by: Gary Flam on Nov 26, 2021, 4:39 PM
Hello, Thank you for the question. When using a two part dosing system, you can always add different amounts as needed in order to raise the levels as desired. You can use our Alkalinity Calculator to fine tune the dosing amounts. Most 2 part systems do not recommend adding more than 1ml per gallon of the part been dose to avoid drastic changes in the aquarium.

Happy Reef Keeping.

I am considering switching salts to Tropic Marin, but have a question about the two versions. The pro version says it works for calcium reactors ? Yet the reg version doesn’t indicate that. I run a calcium reactor but my alk is more inline with the reg version. Any issues with using the reg version while running a calcium reactor?
Question by: Scott on Jun 14, 2019, 2:17 AM
Hey there-

Thanks for reaching out to us and great question! The classic salt mix can still be used with a calcium reactor, however it is best to use lower alkalinity salts since you will be supplementing your tank with the calcium reactor anyways. So it is definitely possible, just significantly easier with the classic, If you have any other questions let us know.

Happy reefing! :)
