SURF8 dimensions: 17" wide by 11.5" tall by 4.5" thick (42 cm wide, 29 cm tall, 11 cm thick).
Operates on both 120V and 240V.
Get the no-overflow advantage of an upflow scrubber: since it is ALL underwater, it can't overflow onto your floor.
Finally a seaweed cultivator and aquarium/pond filter that offers two-compartment alternating growth, cleaning, and redundancy, drop-in installation, reduction or elimination of water changes and nuisance algae, along with almost no-light and almost no-sound, and possibly most important, one-handed harvesting with no disassembly required. It operates the way oceans and lakes do, using algae to do all the filtering and absorbing of nutrients, and truly can replace all other filters in your aquarium or pond.
The SURF8 (tm) is the largest version of the SURF Scrubbers®, which were the world's first floating surface Upflow Algae Scrubbers® (also called UAS®) and seaweed cultivators. The SURF8 is also a Ribbon Scrubber, which is what allows the green hair algae (mostly cladophora "angel hair" seaweed) to be removed from the scrubber/cultivator with one hand without needing to disassemble anything or take anything to the sink. Simply lift up a lid and pull the growth out. And you can feed some of the growth to your fish and snails if you want to (fresh food is best!). The large size of the SURF8 also stabilizes the unit when one light is lifted up.
This SURF8 floating surface scrubber/cultivator has over 96 square inches (600 square cm) of extremely rough Green Grabber® algal growth surface which can grow up to a 1" (2.5 cm) thick block of green hair algae in saltwater. This is about eight small handfuls, and is designed to absorb the nutrients from this much feeding per day:
8 Frozen cubes, or
80 Pinches of flake, or
80 Square inches (500 square cm) of nori, or
22 grams of pellets
The physical size or number of gallons or liters of water in your tank, sump or reservoir does not matter. If you feed more than the above amounts, you can get multiple SURF8 units. Note that if you have rocks which are soaked with phosphate from having been in a problem aquarium,
each 50 pounds (23 kg) of problem rock will add 1 cube a day to your feeding amounts; so be sure to account for this when choosing a scrubber size. For example, if you feed 3 cubes a day, but have 200 pounds of rock that came from a tank with nuisance algae problems on the rock, this rock will add 4 cubes a day to your feeding, meaning that you would need a scrubber for 7 cubes a day. This applies even if the rock was dried out and bleached, because this does not remove any nutrients from the rock (it just kills anything that was living).
The SURF8 combines the exact functionality of two SURF4 units into one larger unit, and does so in about the same total space but with less air tubing and more floating stability than two separate SURF4 units would provide. The LED lights on the SURF8 are exactly the same (and can be swapped at any time.with) the lights on a SURF4, and since each light has a separate power supply, you can operate them on opposite photoperiods if you like. So, for those who have been seeking pH stability, the SURF8 is the first scrubber which will allow you to alternate the photoperiods without having to buy two separate scrubbers.
The SURF8 is designed for larger sumps, but will also fit well on top of dedicated scrubber-sumps, refugiums, frag tanks, displays (if it will not block the lighting), and saltwater ponds. One of the two growth compartments can also be operated solo, by turning off the light of one of the compartments. This allows you to reduce scrubbing capacity when not needed, such as when cycling a new tank.
The SURF8 starts with eight bubble openings at the bottom of the growth compartments, where upflowing air bubbles (from your high capacity air pump, not included) flow up into the two growth compartments and bring aquarium or pond water with it. As the bubbles and water enter the growth compartments they rub the algae-attachment ribbons and get blasted by the super-red 660nm LED light. The bubbles then circle around and around inside the growth compartments, rubbing against the strings and the Green Grabber super-rough rock-hard attachment textures as the bubbles rise up to the water surface. This repeated rubbing of bubbles causes algae to start growing on the strings and textures. The air then goes out of the top of the filter, quietly and with almost no salt spray, and the water goes down and out the eight drain holes in the bottom without any bubbles remaining.
A few features of the SURF8 provide real usefulness and are available on no other algae scrubbers except SURF scrubbers. First, the enclosed growth compartments increase the dwell time of the water and bubbles inside the unit so that they rub the algae many times before leaving the compartment. This actually reduces nutrients (nitrate, phosphate) to a level lower than the outside water, which allows greener growth to occur sooner (lower nutrients grow greener algae) inside the unit, especially in high-nutrient water. In other words, the SURF8 creates a lower-nutrient ecosystem inside itself which is different from the rest of the outside water. Also, the position of the air bubble inlets (below the growth) causes the bubbles to flow up through the growth no matter how thick the growth gets. This is in contrast to waterfall scrubbers, which mostly flow water on the outside of the growth, leaving the inner layers of growth without flow.
Another feature which was highly requested was quiet operation. Since the SURF8 does not attach to the aquarium glass or sump glass, and since it's made of heavy material surrounded by foam, it is one of the quietest algae scrubbers; as a matter of fact it's almost silent (your high capacity air pump will certainly be louder). The two thick and heavy gauge plastic growth containers are connected together by plastic beams, and are coated internally by even thicker and heavier Green Grabber rock and epoxy textures, and then are surrounded on the outside by 1.75" (4.38 cm) closed cell polyethylene foam. This stops virtually all sound from going sideways. And the two 3/4" (19 mm) thick LED lids are filled with super dense polyurethane (the lids are 1.5 pounds each), which absorbs more sound than a rigid structure would, and much more than a non-sealed structure would. Lastly, the path that air has to take to get out of the top requires the air to first go sideways towards the foam, and then upwards along the foam; this allows the foam to absorb any remaining sound exactly the way foam absorbs sound in a studio. So while you may hear bubbling while standing next to it, you will not hear much if there is other equipment or pumps working. And as growth fills the compartments, even more sound is absorbed by the algae itself, like a muffler. Your high-capacity air pump which will probably produce more noise, and that's why there is 10 feet (3 meters) of 3/8" OD (outside-diameter) pure silicone air tubing for you to be able to place your air pump wherever you like, such as in a separate fish room or closet.
Another great feature is the elimination of salt spray. Since the air must come up through the narrow space between the LED lids and the foam, all the salt spray remains in the growth compartment where it is washed away by the water. And if the SURF8 does ever need to be "washed", just push it under the water surface for a few seconds and let water flow over the top (the LED lids are fully waterproof); no need to take it to the sink.
Bubble removal is probably the most-requested feature. Any and all algae scrubbers, whether they are upflow, waterfall or horizontal rivers, have bubbles which must be removed. The internal growth compartments of the SURF8 keep bubbles inside the 2" deep internal water level, only letting water out of the eight small holes at the bottom after the air has escaped out the top. Thus, no bubbles get into the aquarium or sump water; only a little red light, which gets less as growth gets thicker.
The Green Grabber® algal growth attachment surface is so rough and prickly that is might be the roughest thing you've ever felt. A cactus might be sharper, but that's about it. Rough surfaces are critical for allowing algae to attach and grow and thus provide strong absorption of nutrients. The rock-hard protrusions stick straight out 1 to 3 mm. Previous algae scrubber screens were made from "slippery" plastic canvas that is used for sewing and knitting; algae does not attach to it very well. Green Grabber rocky growth surfaces are not plastic at all; instead they are rock hard like rocks on the beach, and they have jagged rough edges and points (don't let children play with them). And the white color of the Green Grabber surfaces reflect as much light as possible, allowing lots of light to reflect back to the algae, which reaches deeper into the algal root sections to keep the roots alive and attached.
The main advantage of the SURF8, or any algae scrubber, is that if you size and operate it properly it can be the only filter for your tank, even replacing water changes. It can, however, also be used with other filters. Some other filters such as carbon dosing (Zeo, pellets, etc) may slow down the scrubber, but nothing will really "hurt" the scrubber except possibly large amounts of algaecide or copper medications. The SURF8 cannot even dry out, since it's always under water; so it's safe in power outages or tank-controller mishaps.
The SURF8 comes with dual power supplies on each LED lid (total of four power plugs), each plug powering four LEDs (total of 16 LEDs). Not only does this provide backup, it allows you to start each scrubber compartment with less light in a low-power mode, which sometimes helps growth start faster in low-nutrient water or new tanks. It also allows you to alternate photoperiods, or to completely turn off one of the compartments if you want to focus the growth in the other compartment.
The SURF8 will run on
both 120V and 240V, and each power supply plug comes with a 10 ft (300 cm) power cord with a U.S. plug. If you require a different plug for your country, you can get four plug adapters at any local hardware or travel store, or online, or you can cut off the U.S. plugs and install your own four plugs from a hardware store. They are simple 2-wire plugs, and are ready to plug into any reef controller. Computer laptop "figure 8" power cords can also be used; they plug right in with no modifications needed.
The SURF8 comes with 10 ft (250 cm) of extremely flexible pure silicone clear airline that is 1/4" (6mm) inside-diameter, and 3/8" (9mm) outside-diameter; this allows you to put your high-capacity air pump in another room or closet if desired. The SURF8
requires a high capacity air pump that can pump at least 20 total liters per minute (0.8 cfm), which regular air pumps that use regular airline cannot do. You will instead need an aquaculture or hydroponics type of air pump. You can pump as much air as you like, however; an 80 lpm pump is no problem, because the bubble-rings on the bottom which circle the air inlets prevent large bubbles from escaping. It is the air bubbles which move water into the growth compartments and up the growth surfaces, which allow algae to grow in the filter. The more bubbles there are, the thicker the algae can grow. Large bubbles even create openings in the algae for light to reach further down into the growth; thus reducing dark areas. The bubble-rings also shield the bubbles from strong powerheads or flow that some sumps have, so that all the bubbles go up into the SURF8 growth compartments.
One powerful air pump which has been tested and works well is the Coralife Super Luft SL-38, which is sold by different names in different countries. And the larger SL-65 puts out even more air. However, although they are very small (the size of a softball), they are noisy and get warm enough that you can feel the heat when you walk by (which is why you may want to place it an another room or a closet, using the 10 feet of included air hose). However there are many other air pumps which will work well; they tend to be sold for hydroponics, aquaponics, aquaculture, koi ponds, septic tanks, and other uses. They are usually much larger and heavier so that they will absorb the sound and run cooler.
One such pump is the HAILEA air pump in the smaller model ACO-9720 which is 25 watts and 30 liters per minute, or the larger model ACO-9730 which is 50 watts and 60 liters per minute. These pumps are completely waterproof, solid metal, and very silent so that you will only hear the scrubber working, not the pump. However they are large (the size of a soccer ball), and heavy (8 or 12 pounds; 4 or 6 kg), and they use lots of thick rubber inside which gives a "new tires" smell for a while. They are available in either 120 volt or 240 volt versions, and are easily found online; the 25 watt ACO-9720 is ok for one SURF8, and will be a bit quieter because of less bubbling; the 50 watt ACO-9730 gives very strong bubbling on one SURF8, and can easily power two, and maybe three SURF8 units. The 120 volt USA versions are available here:

And here is a comparison video:
http://youtu.be/dLAv1Zo9fYM
Each of the two LED lids contains 8 deep red (660 nm) 3-watt LEDs each (total of 16 LEDs), which are attached to an aluminum heat sink which is epoxy coated black to reduce heat; it does get warm but is completely waterproof. The LEDs will give the aquarium or sump a slight red color at night when the aquarium lights are off, but this will occur less as the SURF8 fills with growth. You will
probably need to get at least one timer so you can run the LEDs for 12 to 22 hours per day. The LEDs never needs replacing.
Each growth compartment of the SURF8 will need to be cleaned ("harvested") every 7 to 10 days or when thick with growth. Just lift up the LED lid, grab a handful of algae, and pull it out. You can even feed some of the algae to your fish. In saltwater, you usually do not need to take anything apart, or take anything to your sink, once the growth gets thick. When new however, the growth is slimy enough that you may need to take the SURF8 to a sink (or outside) in order to brush the growth out while holding the unit under running water.

"I have a SURF8x and a Pax N24 on the same tank, and I have to de-tune the Surf because it kills the chaeto in the Pax. The Pax is over 2 feet high, and the Surf is only 4 inches high. And the Surf harvests in about 10 seconds" -- Chuck Lee, Danbury, Connecticut, USA
"The SURF8 is doing more filtering than anything I've had on my tank; I love it!" -- Richard Neal, Santa Clara, California, USA.
"Our SURF8 that we have on our customers tank is crankin' every week, 1/4 gallon of harvest each week. The tank is being fed 3 to 4 cubes a day, and has about 140 pounds new pukani rock." - Damon Buehrer, Aquatic Treasures Reef Store.
