And 9,408,374 as well as Chinese CN203392929U. All the oceans, reefs, lakes and rivers are naturally filtered only by algae, and all the organic particles remain in the water to feed your creatures. Reduce your nitrate, glass cleaning and water changes, and create an environment for living micro-animals to grow inside the scrubber. No more dosing or possible overdosing of chemicals.
And you can use the algae as free food for your herbivores! Get the no-overflow advantage of an upflow scrubber: since it is ALL underwater, it can't overflow onto your floor. Just nice soothing bubbling, like you probably already have in your freshwater tank. And since there are no strings (like our HOG3), it's easier to brush the freshwater growth clean in your sink. This HOG2x scrubber has 48 square inches (300 square cm) of one-sided freshwater algal growth surface, which once growing is designed to absorb the nutrients from this much feeding per day.20 Pinches of flake, or. 20 Square inches (125 square cm) of nori, or. 5.6 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 HOG2x 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 or sump glass, and can be used on glass or acrylic. 1/4 inch (6 mm) to 5/8 inch (16 mm). 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 HOG2x in your sump instead; it will work the same. Compared to the HOG2 which looks the same, the HOG2x has Xtra light LED lamps, and is meant for freshwater tanks with nitrate over 50 ppm.
It will still work with saltwater, but the thicker growth you get in saltwater is better with the strings on the HOG3. The HOG2x has the exact same 6 LED lamps as the HOG3, but with the freshwater Green Grabber growth surface of the HOG2. So this HOG2x is optimized for freshwater growth conditions. The Green-Grabber® 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® 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).And the white color of the Green-Grabber surface reflects as much light as possible, getting almost the effectiveness of a 2-sided growth surface even though it really only has a light on one side of the surface. This is a hand-built Hang-On-Glass® (HOG) Upflow Algae Scrubber® (UAS) with a Green-Grabber. Growth surface, for glass or acrylic.
This is the typical thickness range for most aquariums, and larger 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. You would be better off getting a lower cost HOG.
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. And comes with a 10 ft (300 cm) power cord with a U. If you require a different plug you can get a plug adapter at any local hardware or travel store, or online, or you can cut off the U.Plug and install your own plug from a hardware store. Or just use a figure-8 laptop power cord; it plugs right in, no transformer needed. Comes with 3 ft (90 cm) of vinyl airline, but. That can pump at least 2.0 liters per minute.
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 is the Whisper AP 300 from Tetra, although you may prefer a pump with a control knob to reduce air flow. With any 2-outlet 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, or use a one-way valve on the airline if the pump is lower. Comes with 6 red (660 nm) 3-watt LED lamps, which are attached to a heat sink inside the cover. The LEDs will give the aquarium or sump a slight red color at night when the aquarium lights are off, which is why some people put it in a sump. You might need to get a timer so you can run the LEDs for less than 22 hours per day, but you can try 24 hours (no timer) first and see how it goes.
The LEDs never needs replacing. The HOG2x growth surface will need to be cleaned every 5 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. No hard scraping is needed; just brush it with a toothbrush or larger brush. 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 once you are at your sink.This HOG2x comes with a.
