Slime and Heavy Growth screens for RAINs:

https://youtu.be/OsHaI5bTay8

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. These are the standard screens used in our RAIN models.

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 often 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 and 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 (for knitting needles to pass through), thus making it even harder for algae to attach to it.

Green Grabber 3D printed screens can be used on upflow, waterfall, and horizontal river scrubbers, and are available in these types:

RAIN2 replacement: This is the stock 2mm thick flat version, heavier duty that plastic canvas, 6" wide x 4" tall, and with 2 thick hang-tabs cemented on the top which slide into the pipe of the RAIN2 water pipe.

RAIN2 slime and heavy growth: This brand new screen is an "after market" alternative to replace the stock RAIN2 screen. This screen has screen rails hand-cemented onto the regular flat screen, giving much more area for slime attachment in a small space. Slime has a difficult time holding on to waterfall screens because there is no water supporting it like bubble upflow models have, so the extra space and angled "hiding" areas allow the slime to hold on a few more days before detaching. Similarly, heavy thick growth will let go sooner because the thick growth blocks light and flow, causing the roots to die sooner and detach; the extra attachment areas on this screen will hold on to the dead roots a few days longer if you cannot harvest soon enough. The rails can be on one or two sides of the screen; one-sided rails is good for comparing your growth results on each side. There is more info on this screen on page 95 (figure 32) here: Screen

RAIN-4 and RAIN-8 replacement: This is the stock 2mm thick flat version, heavier duty that plastic canvas, 6" wide x 8" tall, and with 3 thick hang-tabs cemented on the top which slide into the pipe of the RAIN-4 and RAIN-8 water pipe.

RAIN-4 and RAIN-8 slime and heavy growth: This is the same as the RAIN2 slime screen but larger.

All screens include an extra 1/2 inch (1 cm) of screen that goes into the water pipe, and thus the size of the screen is actually taller than the stated size. And the screen even has little "SMF" (Santa Monica Filtration) text partially hidden in the screen, which you can see if you hold the screen over a dark surface.

All screens comes with a 6 month warranty which covers staying together in one piece and not ripping.

No returns; please order the correct one.
