Hi! I need help with a DIY filter media that I can put in my submerged filter. It is a tetra whisper filter. The reason i am asking this is because the "bio-bags" it comes with rip pretty easily and also have carbon in it, which I wish to get away from. Also, I thought I'd like to try it. I had put a new bag in a month (?) ago (kept cycled bag in too) and just took them out to rinse them in tank water to find that the new one had a huge rip. The old one has a small year I already knew about. The DIY media will be used with the blue thing in the pictures below. I will use a cycled bag in conjunction with the new media until it is cycled.
