NikTzo: The media could not be loaded.  Using this to produce MASSIVE amounts of algae and biofilm in my unique setup. I m honestly very pleased so far, and the openings make me believe that there s less of a chance any of my fish will go in there. I also have it backed up as the sole module by a UPC battery since here in Montreal we get 3-5 power outages every single year and some can last days. This allows me time to reach the aquarium if I m not home at the time and remove the device within a few hours to not chop up any overly adventurous fish if the battery runs out before the power comes back. I wouldn’t use anything mechanical in an aquarium without some sort of power backup ever if you are aware your area is prone to power outages. 👍

Mark: It almost overworks. I use this on my 140 and the fish get a great current. Its easy to clean and the magnet works well. Don't recommend for smaller tanks...as it would be far too powerful. 00 gallon or up for sure

Jackie Visser: Looks good, hadn't tried it yet. Just disappointed because it is NOT battery powered like it says

Uncle Steve: It is a bit loose in its cage so difficult to direct. It will not stay pointed where I put it. Others I have purchased do. Moved to 150 gallon with large plants to hide behind. I have it propped on the filter out take so it stays put. Does a great job of preventing dead zones in tank. Moves the water nicely. The blue a bit harder to hide than I had hoped. Need one for the 180 gallon but will opt to find a black one to attach behind the skimmer box. Need one that stays where it is pointed. Summary wont send it back as it works. Unlikely to purchase another as it is loose and obvious.

Jared MJared M: I like that it does what it says, I read other reviews saying it stops working, but maybe someone didn’t properly clean it like it says in the manual/sheet. But we will see I guess

Penguin709: I just wanted a pump for my hydroponic system to keep the water moving. It seems to be doing the job so far. I can hear the hum, but it's not annoyingly loud. The trickle of water pumping through the system is louder than it. The magnet is very powerful (it's held in its place by a magnet from outside the water tank). Like strong enough to hold the pump up through part of my hand powerful. As long as this doesn't give out on me, I'd say this was perfect for what I needed.

Ryan: These are great if you just need the most flow possible for the money. 100gph per $ is about the best you can do, and this has a magnetic mount instead of a suction cup - much better and just icing on the cake.

These are so powerful I'm using one to create circulation in my 10 foot, 1000g pool. Just bought 2 more, one for my reef tank mixing barrel and another one for the pool.

I like that it has an adjustable sleeve to reduce the flow if needed, but I use them at max output.

The only gripe as others have mentioned, is the mounting clamp doesnt have much friction on the pump body, so it can move around and change it's direction over time. Some even said it came out of the clamp completely, but ive never experienced that.

A simple solution is to wrap a rubber band around the centerline of the body. This will keep it in place and won't affect the flow.

Luis R.: Buena bomba, clon de tunze, de buena calidad, por 400 pesos no se puede medir más, ideal donde no requieres flujo bajo, la tuve en un red sea 130 y daba muy buena circulacion, sin duda la volveria a comprar.

Bill: I use this to circulate the water for oxygen exchange in my 72gal bow front. I used this to replace a powerhead which decided to randomly start backwards half the time. This unit is powerful enough to circulate the water without creating a tsunami. My coolie loaches love playing in the current. The unit is quiet, and starts in the correct direction every time. A couple of minor complaints. First, the 'ball-and-socket' kind of mount is a bit odd, and feels like it won't stay where you want it. If you get it into the desired position, and then stick the suction cup which holds the power cord it seems to work fine and has not moved. I wish the whole unit was black rather than having the 'ball' be blue, since black disappears into the tank better. The magnetic mount is the bees-knees - I hated the fact that the old powerhead which used a big suction cup would fall off occasionally creating the sandstorm in the substrate and freak out the fish. I recommend this unit.
