Upflow Algae Scrubber (UAS) with Green-Grabber surface - Magnet Version
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, however you should measure yours to be sure. If your glass or acrylic is thicker than 1/2 inch (6.25mm), you can order the suction-cup version instead which will be available soon.
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. You would be better off getting a lower cost HOG.5 filter HERE
This HOG1 (tm) has over 24 square inches (150 square cm) of growth surface, and is designed to handle this much feeding per day:
1 Frozen cube, or
10 Pinches of flake, or
10 Square inches (62 square cm) of nori, or
2.8 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 HOG1 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 (6.25 mm) to 1/2 inch (12.5 mm). Not more. If your aquarium wall is 3/4" (19mm) or bigger, then put the HOG1 on your sump instead; it will work the same.
This is the first and only algae scrubber you can buy with Green-Grabber (tm) growth surfaces. Green-Grabber surfaces are so rough and prickly that they might be the roughest thing you've ever felt. A cactus might be sharper, but that's about it. The rock-hard protrusions stick straight out, 1 to 3 mm, and some are even 4 mm long. Conventional algae scrubber screens are made from "slippery" plastic canvas screen 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 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, getting almost the effectiveness of a 2-sided screen even though it really only has a light on one side of the surface.
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 HOG1 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. Make sure to put the air pump above the aquarium so that it will not drain any water if it shuts off.
Comes with 2 red (660 nm) 3-watt LEDs, which are attached to a heat sink inside the cover; the cover gets warm on the outside. The LEDs will give the aquarium 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 18 hours per day (not 24!). The LED never needs replacing.
The HOG1 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 will 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.
