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.

Unfortunately one of the sliding tab things broke off during that cleaning. I’ll have to check but do all of the screens have the holes to zip tie them? I’m not sure mine has them

Yes they can all be zip-tied like they were originally done. Or you can clean and epoxy the tab back on fairly easily.

Also that photo with the growth ring shows the screen should be cleaned sooner, all the way down to the white screen holes.

Another new photo of the RAIN4 in position on the adjustable pole mount. Water is fed into the gray 3/4 inch hose barb at the bottom, or, the barb can be removed and a 3/4 inch hard pipe used instead. Also included is a 3/4 to 1 inch adapter for 1 inch hard pipe.

Here is a look inside the RAIN4 dome lid, with all 6 of the GEM5® lights plugged in. The photo had to be dimmed (edited) because the lights are blinding bright 660nm deep reds, and put out 5 watts each (30 watts total), which is almost all illumination because the power supply boxes are safely a far distance away (see www.LEDsafety.org) and do not add any extra heat at all to the scrubber.

Other people's lights, such as the common bolt-on ones from China, have the power supply inside the light, and this makes the lights 60 or 80 watts of heat each, but this is just power supply heat and not illumination, and so the scrubber gets very hot (120 to 300 watts of heat) which makes your sump area a warm swamp.

When a RAIN2 or RAIN4 is new, you only plug in 1 light because they are so bright...

Customer's RAIN4 waterfall scrubber, set way down in a saltwater sump, almost touching the waterline. Since the six GEM5 lights inside the dome lid can operate submerged, any water spray or water level increases (like turning the return pump off), no harm is done to the lights. And if the RAIN tray touches the waterline, it is dead silent with no water drain sound at all.
