MarinePure® GEMS – Ultra-Efficient Biofiltration for Nano & Small Aquariums

*(90g | Filters up to 70 Gallons / 260L)*

Supercharge Your Tank’s Beneficial Bacteria!

These high-porosity ceramic GEMS provide 1,450 in² of surface area – giving nitrifying bacteria the perfect home to:
 Reduce harmful ammonia & nitrites faster
 Lower maintenance by stabilizing water quality
 Prevent "mini-cycles" when adding new fish
 Work in ANY tank setup – freshwater or saltwater


Why Your Tank Needs MarinePure GEMS

🔹 18-20mm size – Fits even tiny filter chambers
🔹 Open-cell structure – 10X more bacteria space than bio-balls

🔹 Place anywhere – Sump, HOB filter, canister, or overflow box


How to Use for Best Results

1️⃣ Rinse lightly (with tank or RODI water)
2️⃣ Place in high-flow area (after mechanical filtration)
3️⃣ Speed up colonization with bacterial starter (like Microbacter7)
4️⃣ See full benefits in 2-4 weeks


Package Includes:

  • 90g (3.2oz) of premium MarinePure GEMS

COOL Pillowcases Worth Buying
Color: Champagne, Size: Queen
I bought these to try out, and I was shocked to find they worked out better than my silk pillowcases. I have atopic dermatitis, and I need a pillowcase that doesn't irritate my skin. I also am having hot flashes and need something cool on my face. These pillowcases are perfect for both my conditions. I plan to buy more in different colors. My sons and husband also like it since they are always hot.
