    Here is a customer's RAIN4 scrubber® in a sump. Note the waterline is touching the bottom of the tray; this eliminates any distance that water has to fall down a drain, and thus makes it dead silent. They tray can even go under water if needed, for room. The waterproof submersible GEM5® lights make this possible (see LEDsafety.org)

    Not shown here is the easy one-handed removal of the dome lid off of the tray, or the entire dome/tray off of the pole mount. This is a patented function of the Rain models.

    Inside of the LED dome cover of a customer's RAIN2, showing 2 of the 4 lights plugged in. One is at the top, and the other side at the bottom, so the screen won't be over-illuminated on both sides anyplace:

    The tray of the RAIN2 and RAIN4 waterfall scrubbers not only catch falling growth from the screen, but also keep the growth growing on the tray. Then it can all be removed easily with one hand by just lifting up.

    The very thin, rough, and white Green Grabber® screen material (shown here on a RAIN4) holds on to growth better than any other waterfall material. Thin is needed so the light from one side can reach the other side, to help keeps the algal roots alive. And the roughness, of course, helps the algae attach longer, without letting go. And the white color reflects more light back to the roots too. And as this photo shows, after a cleaning/scraping, the holes stay full so that it can re-grow quickly:

    Customer's RAIN2 waterfall algae scrubber (patent 10,655,095) in saltwater shows "growth ring" which looks like a donut. Growth rings require strong lights, like our GEM5 lights, and allow thick deep growth with less detachment in the middle:

    Example of good amount of water flow coming off the Green Grabber® screen on a RAIN2 scrubber® waterfall. Flow this strong is not essential, but you do want the water flowing off of the whole screen from end to end.
