Stronti+ is a concentrated Strontium supplement for reef tanks. Hard corals, clams, and calcareous algaes will utilize strontium in their development and production of their coloration and growth and over time your aquarium's water will become depleted. By using Probibio's Stronti+ strontium additive you can keep your tanks levels perfect with the easy to follow dosing guide leading to faster and more colorful coral growth.


  • Helps growth and coloration of corals
  • Provides needed strontium to clams and coralline algae
  • Stimulates growth of hard corals

How to use Coral Vits

  • The strontium diminishes proportionally with the calcium in a reef aquarium, so you can gauge the strontium demand by examining the calcium content.
  • To maintain the development and growth of corals.

I have been ordering Copepods for many years and I never notice any reaction from my fish or corals when I bought from other places not so buying from Pod Your Reef! The copepods were alive and well! You could even see some swimming around in the tank my mushroom corals went crazy! Highly recommend getting your copepods from here!
