Algae scrubbers, otherwise known as "chaeto killers" because of the high filtering capacity compared to chaeto reactors, have the fastest and strongest rate of removal of nutrients from aquarium water of any type of natural algal filtration. All natural reefs, lakes and rivers are naturally filtered by algae.

The RAIN4 is the biggest RAIN, but the RAIN2 was the first; The RAIN2 is smaller and more affordable, and available with 1, 2 or 4 of our GEM5 (tm) lights here:

http://www.Santa-Monica.cc/product.asp?itemid=87

The RAIN (tm) waterfall algae scrubber is the first new design from anyone anywhere since we introduced the first waterfall design in the year 2008. Back then it was simply designed to fit under the tank that we had at the time. It took a lot of time to remove and clean, and had other issues, but it was not for sale so it did not matter.

Since then all waterfall designs for sale by anyone have copied that design. That original design was ok at the time (you can find it posted on forums by searching "waterfall turf algae filter cheap and easy to build santamonica forum"

Well, now it is 2018 and almost all the shortcomings of that original waterfall design have been overcome with our new patent pending RAIN designs. From the Green Grabber® 3D printed screen, to the underwater submersible and safe low-voltage (but high wattage) UL listed GEM5 (tm) lights, to the pole mount super low space requirement mounting system, we really hope you like the RAIN4.

Here is a customer's RAIN4 with the red cap removed. Can you tell what caused the empty spots on the screen, from looking at the growth on the tray?

Answer: The growth got too thick, too fast, before the customer cleaned/harvested it. So it let go and landed on the tray. This RAIN is still fairly new so the attachment is not as strong as it will be later, so more often cleaning is needed when the screen gets thick and heavy quickly. Also, as is typical on new scrubber installations, the nutrients in the water are high and causing this darker, thicker growth.

No worry however, because the RAIN cannot overflow onto your flow, ever, because it's on your sump.

Here is a short version video of our RAIN4 waterfall scrubber in a saltwater reef sump. Why so much growth? Because of the super strong submersible waterproof GEM5 lights (5 real watts each) that do not lower their wattage when operated in the air; they keep full power above or below the water. And the 5 watts is not "equivalent" power like cheap metal frame lights (see www.LEDsafety.org) commonly use; instead it's the actual wattage of each light, which equals 10 watts of other LED lights, each. And there are 6 of these lights in each RAIN4, expandable to 8 lights.

The growth is thick enough to reach the LED dome lid and out of the wire outlet like a vine growing along a pole. In contrast, box style waterfalls like our original waterfall (www.ats2008.org) are a pain to disassemble for cleaning, but with the RAIN all you do is lift the LED dome lid up with one hand, and remove the red cap.

Note that this installation does not show a pole mount, which is included with the RAIN4 and is optional on the RAIN2.

Note also that you will not get this much hair algae growth with your waterfall algae scrubber, whether a RAIN or DIY. You will get less. That's why this was called "The Most". And waterfalls cannot hold on to dark slime growth as well as our bubble upflow UAS models; so even though dark/black slime holds the most nutrients of any growth and does the most filtering, you cannot expect dark slime to accumulate on a screen that is above the waterline.

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:

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.


8098

[SantaMonica]

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...

[SantaMonica]

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.

[SantaMonica]

All other waterfall algae scrubber designs (which we created in 2008; see Ats2008.org) require you to disconnect and disassemble the unit to get to the growth on the bottom tray. This was a problem. The RAIN2 and RAIN4, which we created to solve this issue, allow you to lift off the LED dome lid with one hand so you can observe any growth on the tray, and then you can lift the tray off of the water pipe also with one hand (as shown) to take it to your sink. And you never have to turn off the water flow when doing this.

This new install of a RAIN4 in a saltwater sump, with the LED light dome lid removed, shows:

o Good flow of water across the whole bottom of the screen; less is ok but the whole bottom of the screen should have water flowing off of it.

o The black tray is level with the sump waterline; this eliminates all sound when the dome lid in put back on. The tray can be lowered even further so the screen is below the waterline, so that the water does not fall off the screen and instead flows smoothly downwards.

o The screen can be slid forward (after removing the red cap) and out of the sump with the water still flowing, and without disassembling anything.

o Growth can be seen easily, and hand-removed easily, without disassembling anything.

o The black tray can be easily lifted up off the pole mount and taken to a sink for brushing.

o If power goes out for a few days, the black tray can be lifted up and set down in the water, to keep the algae alive for over a week.

Happy Scrubbing :)

[SantaMonica]

This RAIN4 is ready for a cleaning/harvesting, and shows how low it can go in the sump water, in this case the tray is all under water. This can be done to save vertical space, or to make it dead silent, since the water draining from the tray does not fall at all and thus does not need a drain pipe attached to it.

8600

[SantaMonica]

Another RAIN4 filling in, with the tray under water (see the right side) which allows dead silent operation safely because the GEM5 lights are submersible. This particular RAIN4 needs the screen and tray brushed clean.

8604

[SantaMonica]

New air cooling vents on the sides of the RAIN4. The waterfalling water does a lot of the cooling inside the dome cover, but if the water is turned off these vents take over and allow cool air to enter the dome at the bottom and flow upwards over the GEM5 lights. The shape of the vent covers also blocks almost all red light from getting out.

The RAIN4 (tm) goes down down down into the sump, saving lots of space, and can go down under water if needed.

[SantaMonica]

This RAIN4 (tm) Green Grabber® screen is almost filled in. Note the coralline on the bottom tray, which is not a problem to clean because of how much open space you have when the LED dome lid is removed. And it might look like the tray is setting on a table, but it's actually still in the sump, sitting at water level which makes zero sound.

8644

[SantaMonica]

This RAIN4 is getting started, and looks like it has 1 light running in the middle. The dark slime (from high nutrients in the water) is holding on to the Green Grabber screen as best it can, but still needs cleaning/harvesting every 3 or 4 days until lighter green hair growth can get rooted in the screen. Waterfalls are no match with bubble upflows when dealing with slippery dark slime, but the porous 3D printed screen will hold more of the growth than the old style knitting canvas screens will. This slime situation is a great application for our new Slime and Heavy Growth screens.

[SantaMonica]

This type of slime growth on this RAIN4 waterfall scrubber in saltwater really needs the screen, tray, and pipe slot to be brushed clean every 3 or 4 days (note how much growth is on the tray), and would do better with an optional Slime Screen so the slime can reallly hang on. More light is not the answer, because the light is already strong enough to make a growth ring. More info:

[SantaMonica]

This RAIN4 has very dark slime from high nutrients in saltwater, and could really use a Slime and Heavy Growth Screen. At least, it should be brushed clean every 3 days, and lights run 24 hours.
