Product details
Seachem Reef Strontium – 250mL (376) is a reef aquarium additive designed to restore and maintain strontium levels to those found in natural seawater. Strontium is chemically similar to calcium and is used by organisms that build calcereous skeletons or shells, including corals, coralline algae, and tridacnid clams. This product provides strontium in a gluconate complex form so it can be used in a reef tank without affecting pH.

- Helps restore and maintain strontium to natural seawater levels (about 8 to 10 mg/L)
- Supports organisms that lay down calcereous skeletons or shells, including corals, coralline algae, and tridacnid clams
- Contains strontium as a gluconate complex to increase bioavailability
- Designed to inhibit strontium precipitation and help avoid alkalinity depletion
- Intended to work without affecting pH in reef aquariums
- Gluconate contains no nitrogen or phosphorus
