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 HOG3 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. Multiple units are also good for backup. 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 5/8 inch (16 mm). Not more. If your aquarium wall
is 3/4" (18mm) it might work but you won't know until you try; it would be better to put the HOG3 in your
sump instead; it will work the same.
Compared to the
HOG1.3 and
HOG2 which look the same in
size, the HOG3 is meant for situations which have nutrient or algae problems, even in cases where the rocks
in the display are covered in thick green hair algae. Algae-covered rocks are the most difficult situations
to fix because the photosynthesis of that algae on the rocks is consuming nutrients from the water (often it
measures zero), making it harder for the HOG filter to get the nutrients. To combat this you need stronger
photosynthesis in your HOG scrubber, and that is what the HOG3 is designed for.
The large inside space of the HOG3 growth compartment allows for lots of build up of algae, but most
importantly the 6 LED light provides the strongest photosynthesis of all the HOGs, giving it the best chance
of out-competing the scrubber on your rocks. Also the 6 LED light grows green algae in situations where the
lower power of the HOG1.3 or HOG2 would only grow brown algae. So this HOG3 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. Be sure to follow the special instructions on reducing the light during start-up (by
covering the LEDs with a cloth) because the strong light and white surfaces will photo-inhibit initial
growth in the scrubber if the light is not reduced..
The strings (ribbons) in the growth compartment of the HOG3 are the same strings that are in the SURF2 and
SURF4, and are the heart of the ability of the scrubber to be able to use all the space for initial growth.
The HOG1.3 and HOG2 have to grow outward from the textures before the open-area of the compartment is filled
in; however the strings on the HOG3 allow this middle open area to start growing immediately, and to do so
using 2-sided growth (strings are 2-sided in growth) instead of the 1-sided growth of the textures alone.
Thus the compartment fills much faster with growth, and faster growth causes stronger photosynthesis
(filtering).
The Green-Grabber (tm) algal growth surface is so rough and prickly that it 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. 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. Green-Grabber (tm) growth surfaces
are not plastic at all; instead they are rock hard and have jagged rough edges and points (don't let
children play with them). Green-Grabber surfaces are so good at grabbing algae and letting it grow that if
you have high nutrients you may starting seeing tiny growth spots within hours instead of days. And the
white color of the Green-Grabber surface reflects as much light as possible, for the most photosynthesis
(filtering).
No electrical parts go inside the aquarium; only air. And the air bubbler is already supplied (it's sealed
behind the growth surface), so you don't have to get an airstone. The bubbler is simply vinyl air hose that has
been cut lengthwise, and with cross-cuts, to form little flexible segments that are both adjustable and
open-able to allow for easy cleaning. This HOG3 will run on both 120V and 240V, and comes with a 10 ft (300 cm) power cord with a U.S.
plug. If you require a different plug you can get an adapter at any local hardware or travel store, or online,
or you can cut off the U.S. plug and install your own plug from a hardware store.
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). One powerful pump which works exceptionally well is the Whisper AP 300 from Tetra. You
will need to combine the two outputs into one to feed the scrubber, using something such as the "Tee" air
line tubing fitting from Tom Aquatics. Make sure to put the air pump above the aquarium so that it will not
drain any water if it shuts off, or use a one-way valve on the airline if the pump is lower.
Comes with 6 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 need to get a timer so you can run the LEDs
for up to 22 hours per day (not 24). The LEDs never needs replacing.
The HOG3 growth compartment will need to be cleaned every 7 to 21 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 off of the strings with your fingers. Usually though
you can just reach in an grab the growth. The Green-Grabber growth surface is permanently glued to the
inside cover using epoxy, however a few of the Green-Grabber particles may dislodge during the first few
cleanings, which is normal. Cleaning the growth surface, bubbler, and the inside cover takes about a minute
with a toothbrush.

Trevor Janvier, Canada:
"My HOG3 is working good, and I want another one" -- Christian Aquino, Westechester, Illinois, USA
"Yes the [HOG3] is amazing. I have it in my ten gallon right now. No algae what so ever on the
glass, etc. Water parameters are perfect!" -- Kelly Peissner, North Pole, Alaska, USA
"Been growing like a champ!" -- Mike Barone, Delrey Beach, Florida USA.
"Both the HOG3 and SURF8 are growing bright green algae; the nuisance algae in my tank is
disappearing fast" -- Richard Neal, Santa Clara, California, USA:
Tom Verna in Southhampton, New Jersey, USA:
"So far, loving my new HOG3, definitely seem to have less algae on my glass, which is nice, not as
much scraping as usual. I stopped using GFO, just before installing this, so the HOG3 was kind of,
in a roundabout way to replace the GFO reactor. My phosphate has risen a little compared to running
GFO (fresh) from 0.05 to 0.09 as expected, but my corals and I prefer this method. I'm now not
focussing on low phosphate, but now focusing on just more stability with phosphate level. There's no
swing in phosphate that is normally related to GFO life, so things stay really stable. The rise in
phosphates is not causing any issues as the ATS has been picking up the slack quite well. When I got
this I was pleased with how easy it was to install and use. It takes up very little space and fits
just fine on the sump under the cabinet" -- IUfan on the INDMAS site:
"My two HOG3 units are very quiet when I put them one inch above the waterline. No other filters.
Just the live rock, 2†sand and HOG3’s. They are growing algae like crazy. I empty
each one about once a weak (on different days) and they are FULL when I do. My tank isn't fully
stocked yet, so I may need to get 1 or 2 more later. Meanwhile, inside the tank, I haven't had ANY
nuisance algae since these HOGs kicked in, and I don't use any other filtration, and I've never done
a water change. Needless to say, I am VERY happy with these. -- Sean Whelan, Brentwood, Tennessee,

"Great deal! [HOG3]" -- polo1704 on ebay
HOG3 from Alanreef On the R2R site:
"I love how my four HOG3 units are constructed" -- Tim Caldwell
"All I can say about the HOG3 algae scrubber is WoW, I'm sure glad I saw it advertised on LA Fishguys
youtube channel. It completely wiped out my severe case of Cyano Bacteria in 4 weeks, it is working like a
champ. I was a little skeptical that it would work at first because it's very compact, but I am completely
amazed on how great it's working. Thanks again for the great product" -- John Quezada
Nicolay Oganesian HOG3:
"The HOG3 that i purchased from you is doing really great. The first time it was full of green small
rounded shape of algae, feels like jelly, i dont know what that is. The second and third week after that is
full of green hair algae. Water parameters are great, with readings from hanna checker and salifert testers.
I want to buy more of your products; I'm building a 5.2 meter reef aquarium" -- Yuppy Suhandinata:
"This is just one week after my first HOG3 cleaning; Is growing super thick green algae"
"And this is about 2 weeks growth, compartment completely full, nitrates are at 0, phosphates are between 0
and .25 per API, top layer was touching glass and was really yellow, when I pulled the layer off there was a
ton of algae and it was dark green" -- Nathan P.
"It's been a little over a month since I installed two HOG3 filters on my 165g tank. Any algae that was
growing on my rocks (just one spot) is now gone. Best part, so is any and all cyano!" -- 3Twinklets on
the R2R site:
