Welcome to algae scrubbers. We are the only source for patented upflow scrubbers: U.S. Patent 9,115,008 and 9,708,207. All the oceans, reefs, lakes and rivers are naturally filtered only by algae, and all the organic particles remain in the water to feed the creatures. Reduce your glass cleaning and water changes, and create an environment for living micro-animals to grow inside the scrubber. No more dosing or possible overdosing. No more refilling. No more pale corals from low nutrients, and no more sick animals from high nutrients. Far more powerful than chaeto or refugiums, and does not remove the food particles. And you can use the algae as food!
Get the no-overflow advantage of an upflow scrubber: since it is ALL underwater, it can't overflow onto your floor. And now, all six of the magnets that go in the water are protected by a hard plastic cover inside of the black silicone; this prevents any scrapes or rust if you happen to accidentally let the magnets snap together.
This HOG3xx is a highest power 12-LED version of the original HOG3 which has 6 LEDs, and HOG3x which has 9 LEDs. This HOG3xx also has two power supplies like the HOG3x; one for a low-power 6-LED mode for startup when the growth surfaces are pure white, or for very new aquariums when there are not many nutrients in the water; and the second one to be added-in once growth darkens up the white surfaces.
This HOG3xx, just like the original HOG3 and HOG3x, offers much larger algae-attachment space to hold more growth between cleanings compared to the HOG.5, HOG1 or HOG1x, and is 2-sided instead of 1-sided because of the strings, compared to the HOG1.3 and HOG2 which have no strings. 2-sided allows light to reach further into the growth, and is best for saltwater. The strong magnets attach to thick aquarium walls up to 1/2" (13mm) glass or acrylic, which is a bit less than the original HOG3 can attach to because of the extra weight of the LEDs and power supply cords.
This HOG3xx scrubber has 36 square inches (225 square cm) of two-sided algal growth surface textures and strings, which once growing is designed to absorb the nutrients from this much feeding per day:
3 Frozen cubes, or
30 Pinches of flake, or
30 Square inches (180 square cm) of nori, or
8.4 grams of pellets
The number of gallons or liters of water in your tank or sump does not matter. If you feed more than the above amounts you can get multiple HOG3xx units, or a combination of HOG3xx and SURF units; multiple units are preferred over one larger unit because you can clean one unit per week, and because you'll always have one unit filtering while the other one starts growing again after a cleaning. The magnets attach the outside cover to the inside cover through the aquarium wall, and can be used on glass or acrylic 1/4 inch (6 mm) to 1/2 inch (13 mm). Not more.
The HOG3xx is meant for situations that have severe nutrient or algae problems, even in cases where the rocks in the display are covered in thick green hair algae. In particular, compared to the original HOG3 and HOG3xx, the extra extra LEDs of the HOG3xx provide the highest photosynthesis yet in this size scrubber and is suitable for the highest amount of nutrients (such as phosphate) in the water.
The large inside space of the HOG3xx growth compartment allows for lots of build up of algae, but most importantly the 12-LED light provides the strongest photosynthesis of all the HOGs, giving it the best chance of out-competing the scrubber on your rocks and also cutting through the phosphate in the water as high as 1.0 ppm. The 12 LED light grows green algae in situations where the lower power of the original HOG3, and certainly the HOG1.3 and HOG2, would only grow brown algae or slime. So this HOG3xx model is great for aquariums that have been running for years and are showing signs of old tank syndrome, or in highly-fed predator or NPS corals tanks, especially where the water has very high measurable phosphate.
The Green-Grabber (tm) algal growth surface is so rough and prickly that it might be the roughest thing you've ever felt. 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 2 mm. Old style algae scrubber screens are made from "slippery" plastic canvas that is used for sewing and knitting; algae takes a long time to attach to it. The white color of the Green-Grabber surface reflects as much light as possible, for the most photosynthesis (filtering).
This is a hand-built Hang-On-Glass® (HOG) Upflow Algae Scrubber® (UAS) with strings and a Green-Grabber growth surface, for glass or acrylic 1/4 inch (6 mm) to 1/2 inch (13 mm) thick. This is the typical thickness range for small and some medium aquariums, and larger sumps, however you should measure yours to be sure.
No electrical parts go inside the aquarium; only air. This HOG3xx will run on both 120V and 240V, and comes with a 10 ft (300 cm) power cord with a U.S. plug for each of the two power supplies.
Comes with 3 ft (90 cm) of vinyl airline, but requires an air pump that can pump at least 2.0 liters per minute (.07 cfm), preferably more. A pump that says it can handle 2 or more airstones/outlets, or a pump with 2 tubing attachments instead of one, will be needed. You can have as much air as you like, however; 10 lpm pumps are no problem (although it will be louder).
Comes with 12 red (660 nm) 3-watt LEDs, which are attached to a heat sink inside the cover; the cover does get warm. The LEDs will give the aquarium or sump a slight red color at night when the aquarium lights are off. You will probably need to get a timer so you can run the LEDs for up to 22 hours per day (not 24), although you can start out at 24 hours as see how it grows. A single timer to handle both power supplies is fine. The LEDs never needs replacing.
The HOG3xx growth compartment will need to be cleaned every 7 to 14 days, by removing the inside cover, disconnecting the airline, and taking the inside cover to the sink so you can brush the algae off of the growth surface and the bubbler with a toothbrush, and also off of the strings. Sometimes though you can just reach in an grab the growth, especially in saltwater.
