Aquaforest Filter Floss 20 x 100 cm — mechanical filtration non-woven fabric

The Filter Floss 20 x 100 cm is Aquaforest's mechanical filtration floss, dense and compact non-woven fabric tuned to catch large particles suspended in the water: detritus, uneaten food residues, fecal matter, organic debris. Simple, cheap, and immediately effective, floss is the first filtration stage of any properly designed reef system.

The 20 cm wide by 1 m long strip cuts to the exact dimensions of a filter compartment or filter bag in the sump. Versatile format that fits any reef filtration architecture, from nano to large tanks.

Filter Floss use

Cut: to filter compartment or bag dimensions.
Placement: first filtration stage, before biological media.
Renewal: as soon as the fabric visibly darkens, a saturation sign.
Typical frequency: weekly to bi-weekly based on nutrient load and stocking.
Rinse: possible 2-3 times to extend service life, replace after.

Why good floss matters

Catches particles before they break down into dissolved compounds (nitrates, phosphates).
Improves visible water clarity.
Reduces load on other filtration stages.
Makes sump maintenance easier by concentrating debris in one spot.

Frequently asked questions

How often should I change the floss?

As soon as the fabric visibly darkens — typically 5-14 days based on tank nutrient load and feeding. On a lightly fed SPS reef, floss can last 10-14 days. On a heavily fed tank, weekly change is needed.

Can I rinse the floss to reuse it?

Yes — 2-3 successive hot water rinses extend service life without hurting efficacy. Beyond that, fabric structure loosens and retention capacity drops. The economical price of floss usually justifies replacement over multiple rinses.

Does Filter Floss replace filter socks?

Complementary — filter socks are handy for quick swaps without cutting. Strip floss offers flexible cutting for specific setups (integrated filter grid, DIY sump) where a standard sock doesn't fit.
