    Customer's SURF2 or SURF2x floating on a saltwater display. Can't tell which model without looking at how many red lights there are in the lid though.

    It's a large surface area display, so the Surf does not block the display lighting. Of course you could also float it in a sump.

    Surf models, like our Hog and Drop models, can't overflow like box-style waterfall scrubbers, which often overflow even with an emergency drain (we invented the box-style in 2008).

    And like all of our blacked-out designs, all light is kept inside. you can even sleep next to it. Try that with a box-style waterfall.

    And of course, no 240/120 volts or metal ever goes near the water. Just low voltage, high PAR LEDs. Highest PAR of any scrubber light per square inch of growth surface.

    This is a HOG1x (you can tell by the black LED heat sink at the bottom of the left side) in saltwater. It shows a few interesting things:

    1. The growth is hand-harvestable (in saltwater) once you pull the inside part out of the water. For freshwater, you always need to brush it out with a toothbrush because freshwater growth is much thinner and more slimy.

    2. The growth is concentrated in the middle, where the red light is strongest.

    3. The growth is pushed up against the glass, preventing growth on the glass itself.

    4. The top 2 cm of the inside (wet) part is above the waterline; this recirculates water inside the unit which makes nutrients lower inside the unit than outside, and is great for high nutrient water. Also it runs more quiet because no air bubbles are rising up, and it keeps almost all salt spray inside.

    This customer's HOG3 or 3x or 3xx in saltwater shows a combination of slime and green hair. The Green Grabber® strings have most of growth, and should be cleaned by scraping the strings with your fingers. The Green Grabber rock textures can be brushed in a sink, but don't brush the strings because your brush will get stuck in them.

    For freshwater, the HOG models without strings are best because freshwater only grows super slimey Spirogyro species, and must always be brushed in your sink because it's not thick enough to pull out by hand. So by not having strings, you don't have worry about your brush getting stuck in strings...
