## Description

PENN-PLAX presents the Small World Filter. This filter is specifically designed for aquariums and tanks up to 5 gallons. In addition to our Small World, New World, and Betta World habitats, this filter is compatible with other tanks in the market. It fits all shapes and sizes, and also mounts securely to glass, acrylic, and plastic surfaces. Furthermore, it’s safe for both Freshwater and Saltwater setups. Carbon & Zeolite Mixture: Supercharged with scientifically formulated Carbon and Zeolite Crystals, the media cartridge in this kit absorbs ammonia, nitrites, nitrates, and phosphates in a fast and timely manner, along with removing harmful chemicals and toxins, clearing up discolorations, and reducing foul odors from your aquarium, tank, or habitat. Bio Sponge: In addition to the Carbon and Zeolite Crystals, the included media cartridge also contains a Bio Sponge for physical filtration of larger particulate matter, and biological filtration that optimizes the colonization of anaerobic bacteria. Cleaning & Maintenance: Before placing into your aquarium, tank, or habitat, please briefly rinse the filtration unit with warm water in order to remove Carbon or Zeolite dust. If not done before installation, the water could initially become dark or cloudy. For best results, the disposable media cartridge should be replaced every 2 – 4 weeks, ensuring a crystal clear and healthy environment for your fish. Please Note: The Small World Filter (SWF1), does not come with Air Tubing or an Air Pump, which are Sold Separately. This Aquarium Filter comes with a Mounting Bracket w/ Suction Cups for strong and secure placement, a Disposable Media Cartridge, and a Connector that allows easy connection to standard size air tubing. Measurements: Filter Mounting Bracket with Connector (1.5” x 1.25” x 5”), and Filter Media Cartridge (1.3” x 1.1” x 4.1”).

Review: Try these: they're fantastic! - Update 6/15/18: I no longer care that these are loud. It's by far, the most effective filter I've ever used. My fish tanks are crystal clear, my fish are happy, and these are very easy to switch out for clean filters. I increased the rating from 3 stars to 5. Update: As one other buyer mentioned, these are loud. I actually bought a fish tank and fish to provide "white noise". These are a bit loud for my taste, but are doing a nice job keeping the water moving and circulating in the tanks, and the fish don't seem bothered by the increased current. I will update this review once I see how well it works, but for those thinking of buying: Make sure you have a length of air tubing to replace what it comes with. These arrived with a crimp in the tube, and it prevents air from moving freely.
Review: Great for goldfish bowls and other small tanks - I first discovered these a few years ago when I got a 19-cent goldfish at the pet store. I was determined to give him/her a long life, but I didn't want to invest in a whole big aquarium layout. I knew that an unfiltered bowl was a recipe for disaster so I tried this. It's a terrific system. The little filter attaches to an inexpensive pump you buy separately. Suction cups hold the filter in place inside a bowl of your choosing. The filter is pretty small so I wouldn't recommend a tank that's much larger than 2 or 3 gallons. I am also not sure this device would work on a spherical bowl -- I THINK you need something with at least one flat side. The filters are inexpensive and super super easy to swap out after a couple weeks' use. This little feeder goldfish was one of my favorite pet experiences and I attribute his long life (four years!!!) to his healthy bowl.

### ⭐⭐⭐⭐⭐ Great for goldfish bowls and other small tanks

### ⭐⭐⭐⭐ Works Great!
*by D***H on August 7, 2024*

I won 2 goldfish at the fair and set up this little 2.5 gal nano tank for them. Goldfish dirty their tanks quickly so I needed something small to help filter the ammonia and nitrates from the water. This little filter works great! The suction cups hold it in place well and it keeps the water clear for about 2 weeks before it needs a water change and a month in between a complete cleaning as long as you don't overfeed the fish. So far the cartridges are lasting 4 weeks before needing to be changed out which is a simple matter of popping the old one out and popping a new one in. The only thing I've found it doesn't do that well is filter physical particles from the water such as excess food and fish excrement so it looses 1 star for that, but overall I'm very happy with it and so are my goldfish.
