SUNSUN Cashmere Filter Cotton in Singapore Filtration Setups

At 350x30cm this roll lets you cut filter wool to fit almost any tray, sump or hang-on chamber, which is why we keep it on the shelf for both nano keepers and shop owners. You simply measure the chamber, slice a piece, and replace it once it clogs. In our warm 27-29C water, mechanical floss loads up with fish waste and uneaten food faster than in temperate tanks, so having a long roll on hand means you are never tempted to keep rinsing a grey, exhausted pad.

Use it purely as a polishing and mechanical stage; the dense fibres catch fine particulate that ceramic and sponge media let through, leaving water visibly clearer. We advise treating cotton wool as disposable rather than scrubbing and reusing it, since trapped organics break down quickly in the heat. Keep your biological media untouched and only swap the floss, so you never crash the colony that handles ammonia and nitrite.
