Easy to cut to size
As a beginner, I wasn't sure if this would fit my specific filter model. The tear-off design made it super simple to rip off exactly the amount I needed. No scissors required!

Good mechanical filtration
Does a great job catching food debris and fish waste. My water clarity improved within 24 hours. It is slightly thicker than standard pads, so make sure your filter compartment has enough room.

Great value, very soft
The material feels high quality, almost like cashmere as described. It fits perfectly in my hang-on-back filter. I deducted one star only because it requires a bit of rinsing before first use to remove loose fibers.

Reusable and durable
I have washed and reused this sheet three times now without it falling apart. It maintains its structure well and keeps my tank water crystal clear. Highly recommend for anyone looking to save on replacement costs.

Excellent filtration density
This cotton is incredibly dense yet allows good water flow. It traps fine particles that my old filter missed. The tear-off feature makes it easy to customize the size for my canister filter.

Perfect for heavy bioload tanks
I run a tank with large cichlids that produce a lot of waste. This ultra-filtration cotton handles the load beautifully without clogging immediately. The high-density material is a game changer.
Q: Can this filter cotton be washed in a washing machine?
A: We recommend rinsing the cotton gently under running tap water or squeezing it in a bucket of tank water to preserve the fiber structure. Machine washing may be too aggressive and could damage the density.
Q: Is this safe for saltwater aquariums?
A: Yes, the synthetic fibers are inert and safe for both freshwater and saltwater environments. It does not leach chemicals or alter water parameters.
Q: Does this remove ammonia or nitrates?
A: This product is designed for mechanical filtration, meaning it traps physical debris like dirt and uneaten food. It does not chemically remove ammonia or nitrates; for that, you would need activated carbon or biological media in addition to this cotton.
Q: What are the dimensions of the full sheet?
A: The standard sheet size is approximately 100cm x 50cm (39in x 20in), which provides ample material to cut or tear for various filter sizes from small bowls to large canisters.
Q: How often should I replace this if I am reusing it?
A: With proper rinsing after each cleaning cycle, the cotton can last several months. You should replace it when the fibers begin to break down, lose their density, or if water flow becomes permanently restricted despite cleaning.
