SOLD LOOSE AND SCOOPED INTO PLASTIC BAGS

Seachem Matrix is a highly porous bio-media designed to provide optimal biological filtration in freshwater and marine aquariums. Its structure offers extensive surface area for beneficial bacteria to colonize, efficiently removing ammonia, nitrites, and nitrates, supporting a healthy, stable aquarium environment.

Key Features:

  • High Porosity for Maximum Efficiency: Matrix’s unique, porous structure provides superior surface area for nitrifying and denitrifying bacteria, allowing for efficient ammonia, nitrite, and nitrate removal.
  • Supports Aerobic and Anaerobic Bacteria: This media supports both aerobic bacteria for ammonia and nitrite removal and anaerobic bacteria for nitrate reduction, making it highly effective for complete biological filtration.
  • Long-lasting and Maintenance-free: Unlike traditional bio-media, Matrix requires no replacement or frequent maintenance, making it a cost-effective, long-term solution for biological filtration.
  • Safe for Freshwater and Marine: It is suitable for both freshwater and saltwater aquariums, ensuring flexibility across different aquarium setups.

Dosage and Directions:

  • Usage: Use 250 mL of Matrix for every 200 liters of water. Place in a filter bag or directly in any kind of filter, such as canister filters, sumps, or HOB filters.
  • Long-term Use: Matrix does not need to be replaced unless damaged, making it a one-time investment for effective filtration.

Compatibility:

  • Can be used in combination with chemical or mechanical filtration media like Seachem Purigen or Seachem Carbon for a complete filtration system.

Available Sizes:

  • 250 mL, 500 mL, 1 L, 2 L, 4 L, 20 L, 100 L

Saved my skin during the winter
Such a great multi-purpose product!! I’ll use under my eyes if my skin is dry, or if I’m using an active that I know will dry my skin. I also would slather it on during the winter if I was walking or running outside and I knew it would be windy. It really helped against windburn.

Lightweight SPF that layers well under makeup
Size: 5 Fl Oz (Pack of 1)
This sunscreen feels much lighter than many high-SPF formulas I’ve tried and blends into the skin without leaving a heavy white cast. The texture spreads easily and gives a hydrated finish without feeling greasy, which makes it comfortable for everyday wear on both the face and body. I also liked that it layered well under makeup without pilling. I used this during long outdoor days and it held up well while still feeling comfortable on the skin. The SPF 60 protection is reassuring, especially for travel, beach days, festivals, or daily sun exposure. Overall, this is a reliable sunscreen option if you want strong protection with a more wearable, skincare-like texture.

A Must-Have for Sensitive Skin
Size: 5 Fl Oz (Pack of 1)
recently tried La Roche-Posay sunscreen and I’m really impressed! 🌞 The texture is lightweight, non-greasy, and absorbs quickly without leaving a white cast, which is a big plus for daily wear. It feels gentle on my skin and doesn’t clog pores, making it perfect for sensitive or acne-prone skin. I also love that it provides strong, broad-spectrum protection while still feeling breathable. Overall, it’s become my go-to sunscreen—I actually enjoy applying it every morning because it feels more like skincare than sunscreen. Definitely worth it! I would be honored if you would consider me to receive a PR package. I’d love the opportunity to try more of your products and create authentic content that highlights the benefits of La Roche-Posay skincare. Thank you so much for your time and consideration! Warm regards, Andrea Mohanlall
