Seachem Meridian is a premium natural reef sand harvested from pristine marine environments. With its pinkish hue and ideal grain size, it not only enhances the beauty of marine and reef aquariums but also helps maintain optimal water chemistry.

Frequently Asked Questions (FAQ)
Q: Is Meridian live sand?
A: No, Meridian is not live sand, but it becomes biologically active over time as beneficial bacteria colonize it.
Q: Can I use Meridian in freshwater tanks?
A: No. Meridian is specifically designed for marine and reef aquariums, and its buffering effect is unsuitable for freshwater setups.
Q: Will Meridian affect pH and calcium levels?
A: Yes. As an aragonite sand, it naturally buffers pH and contributes to maintaining calcium and alkalinity stability.
Q: Is the pink color natural or dyed?
A: The subtle pink hue is entirely natural, not from artificial dyes or coatings.
Q: Will it cloud the water?
A: Minimal clouding may occur if not rinsed, but this will clear quickly with filtration.
