Santa Monica Filtration SURF8 Algae Scrubber

The SURF8 is the largest version of the SURF scrubbers, a series of floating surface upflow algae scrubbers with Green Grabber surfaces, and strings for saltwater, designed to reduce your glass cleaning and water changes while creating an environment for living micro-animals to grow inside the scrubber.

The SURF8 combines the exact functionality of the SURF4 and the SURF4x units into one larger unit, and does so in about the same total space but with less air tubing and more floating stability than the two separate SURF4 / SURF4x units would provide. The LED lights on the SURF8 are exactly the same as (and can be swapped at any time with) the lights on a SURF4 / SURF4x, 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 / SURF8x is the first scrubber which will allow you to alternate the photoperiods without having to buy two separate scrubbers.

  • Designed for larger sumps, but will also fit well on top of dedicated scrubber-sumps, refugiums, frag tanks, displays, and fresh and saltwater ponds
  • Has two growth compartments: One of the two growth compartments can be operated solo, allowing you to reduce scrubbing capacity when not needed (ex: when cycling a new tank)
  • 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 (less in freshwater)
  • Quiet, near-silent operation
  • Creates a lower-nutrient ecosystem inside itself which is different from the rest of the water in your aquarium, allowing for optimal algal growth
  • Eliminates almost all salt spray (for saltwater) and allows for minimal bubble production
  • Upflow scrubber technology prevents overflow risk-- since it is ALL underwater, it can`t overflow onto your floor
  • Includes 10 ft (250 cm) of extremely flexible pure silicone white airline that is 1/4" (6mm) inside-diameter, and 3/8" (9mm) outside-diameter; allowing you to put your high-capacity air pump in another room or closet if desired
  • Requires a high capacity air pump that can pump at least 20 total liters per minute (0.8 cfm)
  • Will run on both 120V and 240V
  • Dual power supply with four plugs, each one powering four LEDs (total of 16 LEDs). Not only does this provide backup, it allows you to start the scrubber with less light which sometimes helps growth start faster in low-nutrient water or new tanks, or after a really thorough cleaning
  • Each power supply has a 10 ft (300 cm) UL and CE approved power adapter cord with a simple 2-prong U.S. plug, which can easily be modified
  • Can be used as a stand-alone filter or in conjunction with most other filters
  • Dry-Out proof: Power outages will not affect it since it`s always under water
  • Harvested algae can be used to feed your fish, if desired
  • Includes a 1 year warranty for replacement or repair
  • Each growth compartment needs to be cleaned ("harvested") every 7 to 10 days or when thick with growth

  • Has two LED lids, each housing 8 red (660 nm) 3-watt LEDs (16 total)
  • Comes with dual power supplies on each LED lid (total of four power plugs), each plug powering four LEDs
  • Ability to alternate photoperiods, or to completely turn off one of the LED compartments if you want to focus the growth in the other compartment
  • LEDs are attached to an aluminum heat sink which is painted black to reduce heat; it does get warm but is completely waterproof
  • The LEDs will give the pond, aquarium or sump a slight red color at night when the aquarium lights are off, which will reduce as the SURF8 fills with growth
  • The LEDs never need replacing
  • A timer is required to run the LEDs for up to 12 to 22 hours per day

  • Dimensions: 17" wide by 11.5" tall by 4.5" thick (42 cm wide, 29 cm tall, 11 cm thick)
  • Recommended Water Level: 4" (10 cm) of water to operate in
  • LEDs: Sixteen red (660 nm) 3-watt LEDs total --8 on each lid-- which are attached to an aluminum heat sink which is painted black to reduce heat; it does get warm.
  • Requires a high-capacity air pump, that can pump at least 20 total liters per minute (0.8 cfm), which small low-cost pumps cannot do. Pumps that say they can handle 20 or more airstones, or pumps with 4 tubing attachments instead of one, are best..You can have as much air as you like, however, 10 lpm per inlet (40 lpm total) is no problem.
