This HOG1x with 4 LEDs is a more powerful version of the HOG1 which has 2 LEDs. More powerful light is needed when the nutrients are high in the water (such as nitrate = 40+, or phosphate = 0.2+ ). Note: The higher power LEDs will need to be covered by a cloth when new, because the strong light will over-power new growth in the unit and keep it from growing. Once growth starts, the cloth can be removed.
This is a hand-built Hang-On-Glass® (HOG) Upflow Algae Scrubber® (UAS) with a Green-Grabber (tm) growth surface, magnet version, for glass or acrylic 1/4" (6.25mm) to 1/2" (12.5mm) thick. This is the typical thickness range for small and medium aquariums, and all sumps, however you should measure yours to be sure.
If your tank uses thin 1/8" (3mm) glass such as many low-cost 10 gallon aquariums do, this filter is not recommended because the magnets are strong enough that they might crack the glass.
No electrical parts go inside the aquarium; only air. And the air bubbler is already supplied (its 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 HOG1x 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 1.0 liters per minute (.04 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 more than enough. You can have as much air as you like, however; 5 lpm pumps are no problem. One powerful pump which works exceptionally well for a low cost is the Fusion 700 from JW Pet (which we sell too). It is quiet and has two outputs which are adjustable by turning the control knob. Another even more powerful and completely silent pump, although more expensive and without a control, is the Whisper 300 from Tetra. With either pump 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.
Comes with 4 red (660 nm) 3-watt LEDs, which are attached to 2 heat sinks inside the cover; the cover gets warm on the outside. 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 HOG1x growth surface 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 bubbler with a toothbrush. No hard scraping is needed; just brush it with a toothbrush. 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.
