That is the specific kind I have. They are light blue on one side and dark blue on the other. Do you think it matters if I separate the 2 halves? That is the only way I can get it to fit in one of my filters cartridges
Thanks, they look pretty close to the same, but I wasn't sure if there was some other difference. One of my filters will have several pieces of the stuff in it, so it should be alright, maybe I'll just need to rinse more
