Various RAIN waterfall growth pictures

This is a pretty good example of the textured RAIN2 tray holding growth that has dropped off the screen. For best filtering, the screen should be cleaned sooner, but if not the tray will help.

This RAIN2 (tm) scrubber has the patented LED dome lid removed and shows some overgrown growth in saltwater. Needs to be cleaned/harvested sooner (tray too), because you can see the dead roots (hay colored growth) on the left side of the screen. The growth ring in the middle (from the strong GEM5 lights) however did it's job of keeping this area open for light and flow to continue; if this area had growth it would be even more blocked from flow and light and would have more dead roots and would let go:

Note that dead roots do not occur in bubble upflow models because the growth is always under water.

Also note how easy the patented tray is to clean, compared to box style scrubbers that you have to try to reach down into.

This RAIN2 has grown out to touch the GEM5 lights on the inside of the dome lid. You can see the marks of the individual LEDs in the growth.

This is a side view of thick saltwater growth on a RAIN2 screen (note the old style hang tabs). Don't expect this growth very often; this is a special case.

CJ Aquarium saltwater harvest of the RAIN2 (tm) with four GEM5 lights. Your harvest will probably vary. Nevertheless, feed it to the fish.

CJ Aquarium's RAIN2 waterfall algae scrubber with four GEM5® lights needs cleaning like yesterday.

The patented bottom tray of the RAIN2 and RAIN4 is the easiest to clean of any waterfall algae scrubber. Just lift up the LED dome lid. And if you want to clean the tray in your sink, just lift the tray up too (if it's on the patented pole mount). All other box-style scrubbers require you to reach down into the box and scrape the bottom, that is, if you can fit your hand in. And if you want to take those boxes to your sink, you have to disconnect everything. Not with the RAIN... you can take the tray to the sink without disconnecting anything, or turning off the water or the lights.

This is how to handle slime on waterfall screens which occurs in higher nutrients, which many times is when a scrubber is first added to an older tank.

This RAIN2 has an optional slime screen which has vertical slime rails on one side, allowing you to compare the rail side to the non-rail side. The left photo is without the rails, and the right side is with the rails. Another version of the screen has rails on both sides.

Slime, especialy dark slime like this, does not hold on well to waterfall screens. Even the high-gripping Green Grabber textues which hold better than any other waterfall screen sometimes has trouble. This is because slime has no roots and gets detached by gravity. The slime rails on this screen give much more surface area for the slime to hold on to, however, the screen still should be brushed throughly clean in your sink with tap water (so no algae is remaining) every 3 to 5 days, or else additional growth will have trouble attaching.

If the nutrients in the water come down because of the high filtering of the slime, and growth then turns into green hair algae, the regular stock flat screen (without rails) should be used again.

Here is a ready-to-harvest screen of green hair algae on a RAIN4.
