Best filtration upgrade I've made

This media is incredibly dense yet allows water to flow through perfectly. My tank water has never been clearer. The fact that it is glue-free gives me peace of mind for my sensitive fish.

Great value and very durable

I cut this to fit my custom sump. It holds up well after multiple rinses and doesn't fall apart like cheaper foams. Highly recommended for large setups.

Solid performance

Does exactly what it says. Traps debris effectively and provides great surface area for beneficial bacteria. Took off one star only because it was a bit tough to cut with standard scissors.

Reusable and eco-friendly

Love that I can wash this instead of throwing it away every month. After a good rinse, it looks almost new and continues to perform efficiently.

Perfect for saltwater reefs

No chemical leaching detected in my reef tank. The thickness is substantial, providing excellent mechanical filtration before the water hits my biological media.

Easy to use for beginners

I was worried about setting up my first filter correctly, but this media is forgiving. Just rinse it and place it in the tray. My ammonia levels dropped quickly.

5 FAQ

Q: How often should this filter media be cleaned?

A: We recommend rinsing the media in old tank water every 2-4 weeks, depending on your bioload, to maintain optimal flow without destroying beneficial bacteria.

Q: Can this be cut to fit a specific filter box size?

A: Yes, the media is designed to be easily cut with scissors or a utility knife to fit any standard or custom filter compartment.

Q: Does this replace activated carbon?

A: No, this is primarily for mechanical and biological filtration. For chemical filtration, we suggest using this media alongside a separate layer of activated carbon.

Q: Is this safe for shrimp and sensitive invertebrates?

A: Absolutely. Since it is glue-free and made from inert synthetic fibers, it releases no harmful chemicals and is safe for all aquatic life including shrimp.

Q: What is the expected lifespan of one sheet?

A: With proper maintenance and regular rinsing, a single sheet can last 6 to 12 months before needing replacement due to physical wear.
