This filter cycles water at 175 Gallons per Hour (GPH) for tanks up to 50 Gallons in size. It’s great for Freshwater and Saltwater aquariums, along with a variety of Terrarium setups. Accommodating: The adjustable flow switch allows for increased or decreased water flow at will, which is extremely helpful during feeding times, or use it as needed. The directional flow nozzles allow for additional tank customization and convenience. Furthermore, the filter utilizes 4 suction cups, allowing for both vertical and horizontal mounting positions.

Instead of two separate units, this filter combines both functions: simply connect the Air Tube and Air Muffler to the Flow Nozzle, and follow the included instructions. Please fully submerge and fill filter with water before turning on.

Review: 5 years of service and still going strong - Let's start this very simple. This is a top tier filter for 40 dollars ,heck, I'd pay 60 on a bad day. Out of the box it is quiet and effective. Very easy to clean once it's disassembled. After 5 years: it opens easier for sure. I've recommended this filter to everyone I know. I came back to this page to purchase two new ones. Not because my original quit functioning but because it's a little loud after being in a sand/silt bottom tank for 5 years. I will retire this one to my plant tank as it is still a great filter but would be horribly loud for a pet to live next to. More details about it's life: I've abused this filter. It's been overloaded, underwatered, at one point my tank cracked and it ran dry for 3 days while I was on vacation. (one year in) I only ran the carbon portion for about a year, it was extremely difficult to open and refill. Happy to say the filter works great without it. The internal construction is simple and easy to clean making upkeep a dream, just pop the head off and fill your sink with water. Turn the filter on and swish it around. At one point I used the top portion as a pump to do water changes. Just fit some clear tubing on and into a bucket. It is very versatile even in ways it wasn't meant to be. This filter has had a long long life and has proven to be probably the most durable thing I've ever bought. Happy retirement little guy.
Review: Awesome, compact, reliable little filters! - These little filters are awesome! I have tried several other internal filters, but always come back to these. I use two of these in my 20 gallon freshwater aquarium with fish and live plants. These filters are very powerful and you can adjust the flow. They are compact, yet can hold custom media. They are also very quiet. Did I mention they are very reliable too? I have used them for several years now with no problems. Easy to take apart and clean as well. I highly recommend these little filters. You will not be disapponted!

### ⭐⭐⭐⭐ Can be customized, decent for the price, but has several weak points
*by B***L on October 3, 2019*

I bought this as a secondary filter in a larger tank to polish out some tannin staining and fine particles. I removed the included media, cut the sponge in half, added a layer of polishing floss, some ceramic media then a small bag of bio chem zorb. Its working great, it could serve in a smaller tank (like 10G) as a primary filter if set up right. Its very quiet. and has been very effective even with the media swap it still has decent flow. About the "fish eating bottom intake hole": Mine came with a removable guard, I'm considering gluing it in place (regular crazy glue is aquarium safe) but it seems to stay put. I don't know if this is a new update or if they fell out in shipping for others (its a small disc) Weak points: The spray bar: it slides in place, would have been better if it was twist on, or locking, for long term use I think I will just glue it with some silicone later, I have bumped it a couple times and it fell off and it sinks to the bottom. The plastic is on the thin side. The Cord length is fine for short tanks but short enough to limit choices on placement in a tall tank. The suction cups hold glass well, but every time I try to remove it they stay stuck to the glass and separate from the unit. The bases are small, and material flexible. Its not hard to put them back on but its annoying to have to do it every time. Even with these weak points its a great buy for the price and very useful. It would be worth getting an extra as an emergency backup in case your main goes out.
