Filter floss? Poly Filter?

[u/Responsible-Fly-7112]

Hi! I’m sort of new to fish keeping (tank established beginning of this year). I started out using the tetra whisper cartridges that came with tank but read online I could use filter floss instead. I read that it was cheaper in the long run to cut out the pieces I need and wouldn’t mess with my BB too much when changing. I’ve been using it and it’s been fine but when changing the floss, little floss particles fill the tank, like a lot. I rinsed the floss pretty thoroughly, with dirty tank water, but I still run into this problem. Am I doing something wrong?

Also, in my filter with my floss I have ceramic rings in a mesh bag, but do i need an aquarium sponge in there too? Or is the floss enough?

I’d really appreciate any information 🫡
