From the creator of the original roughed-up plastic canvas screen in 2008, comes the first new type of screen ever available for you to buy just for scrubbers: Green Grabber® screen. This screen comes two years after the introduction of our Green Grabber rock hard attachment material that we use in our SURF, HOG and DROP scrubbers, and is 3D printed in plastic that is FDA approved to be food safe.

The color is ultra white; much whiter than the "sort-of" white that most plastic canvas looks like. White is needed to reflect more light back to the growth, especially when the growth is thick and needs as much light as possible to keep the "roots" illuminated and living.

The holes in the screen have been enlarged a bit (compared to 7-point plastic canvas), to allow more light and flow to go through the screen, and to allow the screen to hold on to slime better. New growth starts out as slime, so this allows the screens to mature faster. And if your particular tank keeps growing slime for a longer period of time as some do, these Green Grabber® screens will hold on to it better than ever so you can harvest the most of it.

The Rough 3D (tm) technique of 3D printing these screens is the opposite of what most 3D printing people want; they want smooth surfaces with no holes or other imperfections. Rough 3D however is a patent-pending printing process that makes the individual legs of the screen have different thicknesses, sometimes even with tiny holes in them, and makes lots of irregularities and little threads, all of which allows algae (especially slime) to hold on better, quicker. Regular plastic canvas has none of this, even when it's very roughed up. And regular plastic canvas is made with plastic that is much more slippery from the beginning (for knitting needles to pass through), thus making it even harder for algae to attach to it.
