FAQ
What is the purpose of strontium in reef aquariums?
Strontium is incorporated by corals, clams, and other reef-building invertebrates into aragonite, the mineral that forms their skeletal structures. It helps support healthy skeletal development and growth in reef organisms.
Is this product safe for use in marine aquariums?
Yes, this product is specifically formulated for reef aquariums and is free from harmful organic additives like EDTA, gluconate, or polygluconate. It is safe when used as directed.
How does this strontium solution compare to others on the market?
This solution contains over 50% more strontium than most competing products, providing a higher concentration for effective skeletal support in reef invertebrates.

Kylie Brown –
I’ve used this strontium solution for several months in my reef tank. My corals have shown better skeletal growth and coloration. No signs of cloudiness or residue. The concentration is noticeably stronger than other brands I’ve tried.
Sophie Randall –
Great product. No organic additives, which is a big plus for reef health. My clams are more active and my polyps are more robust. Easy to measure and mix with the tank water.
Elizabeth Nolan –
Works well in my 120-gallon reef tank. I’ve noticed improved coral structure over time. A bit more expensive than some alternatives, but the performance justifies the cost.
Ryan Hamilton –
The formulation is clean and free from common contaminants. I appreciate that it doesn’t contain EDTA or other organic materials that can build up in tanks over time.
