Full Details

Red Sea Reef Foundation Manual


Red Sea's Reef Foundation system has been designed to help promote coral growth and coloration while maintaining the health of the coral.


When corals grow, amounts of calcium, alkalinity, and magnesium will be consumed by the coral to create its calcium carbonate structure. With just a couple small corals the amount of elements that will be consumed can be replenished by water changes, but after corals start growing, or you add more the need to supplement and replenish the elements being consumed will arise. Calcium, alkalinity and magnesium will be consumed the quickest and the Red Sea Reef Foundation System uses high quality components letting you replenish the basic trace elements that are being consumed. 


Reef Foundation A: 1 mL will raise the Calcium level of 25 gallons by 2 ppm.

Reef Foundation B: 1 mL will raise the alkalinity of 25 gallons by 0.036 meq/l (0.1dKH).

Reef Foundation C: 1 mL will raise the Magnesium level of 25 gallons by 1 ppm.

    Very good product I recommend them
  • Works as Advertised By Charles on 3/9/2017

    I have a small 24g AIO aquarium and I didn't want to deal with mixing two part etc. I had gone for 5 years with only monthly water changes of 25% and some of my elements were way off as my LPS has grown huge in the tank. One note: I would only use this on 50g or smaller, ideally 30g or smaller. Especially if you need to raise magnesium a lot like i did. It took almost a whole bottle of mag over a month to get the magnesium up from 1060 (which is admittedly super low). I dose once a week in an LPS and softie tank and everything is very happy. Red Sea also sells a three in one test kit for all of these elements. I bought both and the test kit is nice and easy to use. It also gets the same readings as my Salifert test kits

Product Questions

Is it normal for the calcium bottle to sound like it has gravel shaking around in it?
Question by: Joel on May 25, 2017 4:58:00 PM
As this product is made from crystalline calcium salts, and due to the concentration of material, it's not unusual to sometimes have a little extra salt left in the bottom which is not dissolved completely. The solution is still completely usable and does not indicate a problem with the solution.

Have a great day!
