Pawfly 4 Pak Aquarium Filter Media Pad voor Fish Tank Filters Aquarium Filter Media Spons Filter Floss Roll voor Sumps Vijvers Hydroponics Zwart Schuim Floss voor Waterfiltratie, 16 cm L x 14 cm B

Nowhere near the thickness stated due to being supplied vacpacked.

Comes really tight packed and I thought it was too slim, but in 4-5 hours it was grew in size to a right thickness. I am currently using it as the secondary set of filter pads and so far it's worked well for me.I have made a few filter pads now by cutting them to size that fits my filter. The filter is medium grain, so don't expect it to filter very fine, but it was just the right one for me.Overall, at the price of £6.99, 4 sheets can fit a big filter and 2-3 replacements can be made. With that, it is a good value for money.

Arrives very flat in vacuum packaging. After opening and separating the sheets, they puffed up fully in a few hours.Fine to medium coarse foam, cuts easily with scissors to fit your filter.Ideal biological filtration media.
