Premium Grade, High Alkalinity

  • Naturally harvested salt from the Red Sea
  • Elevated levels of foundation elements
  • Includes necessary minor and trace elements


Balanced Foundation Elements: Contains elevated levels of Calcium, Alkalinity, and Magnesium, critical for coral structural integrity and biological functions. These components help maintain a robust reef.

Optimized Alkalinity: With an Alkalinity of 12 dKH, Coral Pro Salt supports mixed reefs and SPS frag tanks. It ensures pH stability and enhances various biological processes, including skeleton formation and photosynthesis, contributing to the overall health and sustainability of the reef.

Fast Dissolving: Enjoy the convenience of quick dissolution, making water changes efficient and hassle-free. No post-water-change adjustments needed.

Comprehensive Elemental Composition: Emulating the complexity of natural seawater, this mix is enriched with over 70 trace elements. It emphasizes the foundation elements - Calcium, Alkalinity, and Magnesium, crucial for maintaining pH stability, seawater ionic strength, and supporting essential biological processes.

Sustainable Growth: It provides a consistent supply of essential elements, overcoming the limitations of closed system aquariums. This ensures continuous and healthy coral growth without the need for frequent adjustments.


Red Sea Coral Pro vs Red Sea Salt (when mixed to 35 ppt salinity)

Both Coral Pro and regular Red Sea Salt use the same raw materials, including the unique Sodium Chloride harvested from the Red Sea. The biggest difference between these two salt mixes is the concentration of foundation elements. Coral Pro Salt contains elevated levels of foundation elements set for accelerated coral growth, while Red Sea Salt contains natural levels set for mature aquariums and enhanced coral coloration.

Are you guys not selling the small buckets anymore for us that have smaller tanks?
Question by: Ashley on Dec 11, 2023, 9:36 PM
Hey there,
Thank you for reaching out to us. . WE do have 16 gallon and 50 gallon bags but the smallest bucket would be a 148 gal. Please let me know if you need anything further.

Hi I’m on a well I have no softener ph out of the tap is 7.8-8 depending on time of the year and it is relatively hard why is it nessecary to run my water through a RO/DI system stripping out all the minerals that are keeping the ph where it is only to have to turn around and replace them with supplements
Question by: Brian on Oct 28, 2017, 12:18 PM
Hi Brian, thanks for reaching out!

The reason RODI is recommended for mixing saltwater is that it filters out many unwanted dissolved substances from your tap water other than minerals. This is even more important to use pure water for top-off because anything contained in your tap water is left behind as it evaporates. This can lead to a build up of potentially harmful substances like nitrates, phosphates, pesticides etc. It also gives you complete control over your water chemistry since you are not adding unknown amounts of dissolved minerals along with those included in your salt mix.

How long can this salt be mixed and stored ?
Question by: gary on Dec 20, 2016, 11:44 AM
Great question!
If it is mixed longer than 4 hours before adding to the tank there is potential for the precipitation to occur. They recommend only mixing as needed before use. Feel free to let us know if you have any further questions!

I've noticed the alkalinity is elevated to 11-12 range, I havnt seen any information of keeping it at that range, mostly 8-9 range. It's 11-12 dkh still safe for sps and LPs?
Question by: Pavel Bragin jr on Nov 8, 2016, 11:42 PM
Great question! Optimal levels for Alk in the reef aquarium is 2.5-4 meq/L or 7-11 dKH. This salt is perfect for those with a lower coral demand for Alk/Ca where water changes alone can help maintain those levels. :-)

This PRODUC Is Safe To Used With Fish As Well....
Question by: ivan avina on Jul 20, 2016, 4:38 PM
Hi there,
You can use Red Sea Coral Pro salt with a fish only tank if you wanted to. It does have some elevated elements which you won’t really “need” and does cost a bit more than the standard Red Sea salt.

Do you guys sell the 55lb sack of salt?
Question by: Erik Dowey on Jul 5, 2016, 6:58 PM
Hi Erik,

As of right now we carry the 55 gallon bucket and 175 gallon bucket. We don't yet have the new 175 gallon (48.5 lb) refill bag.
Answer by: Valerie on Jul 6, 2016, 12:13 PM
In the directions for Red Sea Coral Pro Salt it says not to mix longer than 4 hours but in the Red Sea Salt mix it does not state this, why should it not be mixed more than 4 hours? what will happen if mixed longer than 4 hours? what is considered mixing then? would having a power head moving the water be considered mixing?

What sea salt do you use or feel is the best and why. I have used reef crystal instant oceans but have been told Red Sea coral is better. Is there really enough difference to make a change. I have 225 reef tank been up running 10 years thanks for your remarks. Ron
Question by: Ron on Mar 10, 2016, 2:13 AM
Great question!
We have had great luck with the Red Sea Coral Pro with the added elements where it has reduced the amount we need to dose for trace and calcium, alkalinity. Another great option we have used is the HW reefer. Both will have added elements to help support more diverse tank. Feel free to let us know if you have any further questions!

What water do you recommend? Is DI ok to use?
Question by: Hunter on Feb 7, 2016, 8:33 PM
Great question!
Ro/DI water is recommended whenever adding water to salt mix to start with pure water. Feel free to let us know if you have any further questions!
Answer by: Connor on Feb 10, 2016, 6:02 PM
When making salt water should it always be made at hand if i have a contaner or salt water should just be made with in the few hours of mixing it???
Question by: rocky on Mar 14, 2014, 3:51 PM
Hi Rocky,
Its easy to have it mixed and ready to go, but there isn't any chance you can mix it as you need it with most salts. The Red Sea Coral Pro in particular actually recommends that you use it within a few hours of mixing it. Letting it sit won't hurt it, but it will get a little cloudy the longer it sits.

I am new to marine tanks can I use this salt for cycling and then I will add fishes and on down the line I will add a couple of corals. is this one better or Reef crystals salt?
Question by: Ronn on Sep 21, 2013, 10:36 PM
Hey Ronn,
If your just starting a new tank and you don't currently have any corals, then I would suggest using the regular Red Sea Salt. The coral pro salt has elevated levels of calcium and alkalinity that wouldn't be of use without corals in your tank.
