(Note: Algae growth is not guaranteed or warranted). This HOG.5 scrubber (tm) has 12 square inches (75 square cm) of algal growth surface, which is designed to absorb the nutrients from this much feeding per day: 0.5 Frozen cubes, or 5 Pinches of flake, or 5 Square inches (31 square cm) of nori, or 1.4 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 HOG.5 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 up to 1/4 inch (6.25 mm) thick. Not more. If your aquarium wall is 3/8" (9mm) or bigger, then put the filter on your sump wall instead; it will work the same. No electrical parts go inside the aquarium; only air. And the air bubbler is already supplied, 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.5 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. You will need to get a timer so you can run the LED for up to 22 hours per day (not 24). Requires an air pump that can pump up to 1.0 liters per minute (.04 cfm), which low-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.

Great product
This is a great product! Took a little over 2 weeks to start buildings algae but it has lowered my nitrates to zero. I would highly recommend getting a bubble pump to push bubbles through it. Doesn’t have to be an expensive one. The first one I got from them was defective, but they quickly got a new one out to me the same day.

My tank is the best it's ever been
This has been on my sump for about month. My tank is the best it's ever been. Algea is disappearing in the display tank. Corals are looking great. The alga growth in the scrubber really took off this week.

Not sure it works
Update 2: My 5 gallon Nano with 2 small fish is doing great after a month with the scrubber. Make sure to give it some time to work. The only downside I see now is the noise it makes. I never thought I could run a nano and keep the nitrates and phosphates so low without running GFO or a refugium.Update: After a month I have some algae growing in the skimmer. I have seen little to no effect on Nitrates, but Phosphates are very low.I don't think this is working as intended. It grows Algae on the tank glass inside the scrubber but very little on the actual grow mat. I'm using a whisper 20 air pump and I tried light periods of 12 - 20 hours. I will update positively if it gets better, but for the build quality and results, I wouldn't spend money here.

Best filtration system I've used so far
Works extremely well in my small salwater tank. I have lots of live rock and had a bad algae problem. I installed the HOG and turned off my aquarium lights for a little while. I figured that I didn't want the tank lights competing with the algae scrubber lights. Wow! It produced very thick mats of green algae. Like I said, my tank was pretty dirty to begin with. I cleaned the scrubber every few days at first while also cleaning all the excess algae out of my tank. Once the rocks were clean I turned the tank lights back on. Now the algae is not coming back but is instead growing inside the scrubber.I measured an increase in my oxidation-reduction potential (ORP) I ran ozone a few years ago until the ozone controller broke and I never had it replaced. Nothing I did ever raised my ORP until I got this scrubber. Now I don't think I'll consider going back to ozone. This seems so much more natural.I don't feed my tank the algae that is grown but you can if you want. I have a very small tank with mostly crabs and snails and just throw the algae away. However if you have some tangs you can feed them the algae that grows making a self sustaining ecosystem. Great idea SantaMonica. Keep up the good work!

Great nitrate and phosphate remover!
Mine works great! Minus one star because it’s just not very attractive on the side of a nano...but it looks better than hair algae allOver my rocks;)Definitely works! I used a little larger air pump, and green hair algae inside the filter. Started right away...

don't waist your time or money
can't tell it makes any difference in nitrate level. waist of money
