Swell replacement foams are perfectly compatible with the Fish Mate GUV Filters, including the 10,000/15,000 and new 20,000 model.
These foams are made to the same high quality as the brand names, but because they are part of Swell's own brand range offer great savings on price, without compromising quality.
The pack includes two filter foams one coarse (black) and one fine (blue). They work together to ensure that not a single grain of waste or debris remains in the water. The 'bumpy' textured surface of each foam means that the water is exposed to as much media as possible.
