FAQ: Can I use Seachem Reef Strontium™ with my fish or corals?

You can!  Reef Strontium™ is specifically formulated to support coral growth, and is perfectly fine to use with fish or invertebrates.  If you are maintaining a fish-only system (FOWLR aquarium), it is unlikely you will need to regularly dose strontium to maintain ideal levels, and it is not recommended to regularly use strontium gluconate (the form in Reef Strontium™) if you do not have corals which utilize this form of strontium. Strontium gluconate is NOT HARMFUL to fish, but if corals are not using up this strontium, bacteria in the water column will do so instead, leading to slight haziness in the water.
