Was wondering if anybody has any experience GH coco mats? I was testing my new set up with flood and drain. After flooding the tray with coco mat i noticed a few days later this slim on my pump filter?? I'm guessing it's from the mat, i was told no need to rinse. The mat feels like rinsing wouldnt help, kinda stiff.. Just curious what others are doing with there mats.
