Meridian

🧪 Usage Instructions

Initial Setup

1. Rinse gently with clean water to remove fine dust before use.
2. Add to the tank to create a sand bed depth of 1–2 inches (2.5–5 cm) or more, depending on livestock needs.
3. Fill the tank slowly to avoid disturbing the substrate.
4. Once water clears, proceed with cycling or stocking the aquarium.

Maintenance Dosing

• Do not aggressively stir the sand in mature tanks to avoid disturbing beneficial bacteria or releasing trapped gases.
• Perform occasional light vacuuming of the surface layer only to remove detritus.
• No need to replace unless redesigning or upgrading the aquascape.

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.
