giddyup Posted July 27, 2023 Share Posted July 27, 2023 I buy fibreglass filter from the pet shop for my fish pond. It comes in a large sheet and I cut it into smaller pieces to fit inside the tank, but find it really difficult to cut. Scissors won't do it and even a Stanley knife struggles. Any tips?

Lacessit Posted July 27, 2023 Share Posted July 27, 2023 You need tailor's scissors, the really big ones. 1 Link to comment Share on other sites More sharing options...

Fortunately only need to replace the filter every 6 or 8 months. Link to comment Share on other sites More sharing options...

How dense is it? Maybe using a hole punch in the line of cut beforehand would help. Link to comment Share on other sites More sharing options...
Crossy Posted July 27, 2023 Share Posted July 27, 2023 I think last time Madam used my hedge clippers ???? At least they can be sharpened. 2 Link to comment Share on other sites More sharing options...
OneMoreFarang Posted July 27, 2023 Share Posted July 27, 2023 And depending on how you cut it wear a mask. As far as I know it is bad if you inhale small particles of it. 1 Link to comment Share on other sites More sharing options...

worgeordie Posted July 27, 2023 Share Posted July 27, 2023 First of all it's not fibreglass , it a kind of synthetic wool , i cut it with ease with a largest size of scissors ,even sometimes smaller ones when i cannot find the large ones , no difficulty at all, so no idea what problem you are having , you can even rip it apart if you have to.... regards worgeordie Link to comment Share on other sites More sharing options...

I bought from a different shop this time and it's only about an inch thick, normally it's about 3 inches thick. There's no label on the bag but I think it might be some kind of polyester.

I bought from a different shop this time and it's only about an inch thick, normally it's about 3 inches thick. From your photos it's exactly like the stuff I have been buying for years, its synthetic wool , I know because I used to be an Aquatics wholesaler in UK , and have sold tons of the stuff, it's actually made for the clothing industry to be used in batting and in making quilts etc,main use, you either have very weak hands or are not trying hard enough , fiberglass would not be used in aquatic filtering as particles would get in the fishes gills, it's a synthetic wool. . regards Worgeordie Link to comment Share on other sites More sharing options...

Yeah my bad...I assumed it was like jap matting but now see the pics you later put up I cut that stuff with a decent pair of scissors. This is how you cut Jap Matting (skip to 9 mins).
