This is the first larger Hang-On-Glass version of the standard HOG.5, HOG1 and HOG1x algae scrubbers, which were the first HOG scrubbers available. This HOG3 offers much larger algae-attachment space to hold more growth between cleanings, and it is 2-sided instead of 1-sided because of the strings; 2-sided allows light to reach further into the growth. Also, stronger magnets attach to thicker aquarium walls up to 5/8" (16mm) glass or acrylic.

Compared to the HOG1.3 and HOG3 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..

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 HOG 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.

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.

Specifications

  • LEDs: Six red (660 nm) 3-watt LEDs
  • Requires a standard air pump that can pump at least 2.0 liters per minute (.07 cfm), which medium-cost air pumps can usually handle. Pumps that say they can handle 2 or more airstones/outlets, or pumps with 2 tubing attachments instead of one, will usually be needed. You can have as much air as you like, however; 10 lpm pumps are no problem.
