Diy Replacement Filter Media For Hob Filters?

[slowcountry]

I have 5 different tanks and I find that filter media is starting to get expensive. I have 1X Aqueon 55, 2 Tetra Wisper 10, 1 Tetra Wisper 20, and 1 Penguin 350 HOB filters. At one time, I had purchased some filter sheet material and sewed two pieces together to fit in the Aqueon filter box. The problem was that the material was too course and did not filter out the smaller particles.

Has anyone worked out an affordable solution for these types of filters?

I'm trying to research on scotch-brite heavy duty pot scrubers as a filter media

could have swore I read about using them here, bought some at sams but kinda afraid to use them since I don't know what they are made out of.
