SantaMonica Posted October 16, 2020 Share Posted October 16, 2020 Customer's Green Grabber® screen from a RAIN2 waterfall scrubber in saltwater. The closeup shows the Rough 3D (tm) printed 2mm thick screen (rough on both sides) that comes with the RAIN2. You can see the tiny threads that go inside the screen holes; these help hold on to growth, especially slime growth which detaches easily from slippery screens made from knitting canvas plastic. Green Grabber screens are instead made of FDA food-safe rigid plastic that is not slippery. Also visible are the two tabs which slide into the RAIN water pipe slot. Link to comment
