Best small filter I've ever used
Date: April 6, 2007
"I've had this teeny tiny filter on a teeny tiny 2.5g tank in my office for about 6 months, and it is fantastic. It's virtually silent and so efficient - the water is absolutely sparkling clear all the time.
It also has a very adjustable output flow for such a small filter, which is good because I have a paradise fish who likes to swim in the current of the filter, but doesn't enjoy a tsunami effect in his itty bitty tank.
I've kept tanks of all sizes since I was a kid, and I've used all sorts of filters, and I've never found a small one to beat this little guy. It keeps my tiny tank as clean as my canister filter keeps my larger tank. I've been very, very impressed."

Great Little Filter
Date: January 5, 2009
"I bought this for my 2.5 gallon mini-tank where I house African Dwarf Frogs and it has been a great purchase. The water stays crystal clear and it is small enough to fit nicely in the back of the tank. The filter cartridges are easy to replace (and cheap!) and the clear casing allows you to see when they're dirty. Overall, this filter has been a great improvement to my tank over the one that it came with. I highly recommend it if you have a small aquarium."

Quiet and effective
Date: December 5, 2008
"This is one amazing little filter. I have it in my 2.5 gallon mini tank, and I have nothing but good things to say about it.
First, it is very quiet. It only creates a very low humming sound once it gets working.
Second, the adjustable flow valve is a great little addition. When I had it on full flow, it made the tank look like a washing machine! But once I turned it down, it was perfect. You can even almost close it for fish like bettas that don't like fast-moving water.
I also like the clear casing. It makes it slightly less noticeable behind my tank.
All in all, a great little filter for little tanks."

A little filter with big power!
Date: November 17, 2008
"This is the best filter I have ever used. It's super quiet (even quieter than the Whisper filters IMO) The casing is fairly narrow depth-wise, and clear so it's hardly noticeable behind the tank. The filter pads are easily accessible, changeable, and cheap to boot. I have mine set up on my 2.5 mini bow for my betta and on the lowest flow setting it just has a small ripple effect on the surface. Within an hour of installing it the water went from cloudy (because of the new gravel I had put in) to crystal clear.
My only wish is that it came with some ceramic media for bacterial filtration."

Highly Recommend!!
Date: October 1, 2008
"I have the Marina 1.77 gallon Goldfish starter kit, and just wasn't happy with the filter that came with it. I have two African Dwarf Frogs (Fred and Ethel) and a small albino cat fish (Phelps) in the tank. The filter that came with the kit was okay, but just okay. Upon the recommendation in the reviews on this website, I purchased the Red Sea Nano. All I can say is WOW!! It took less than 24 hours for the water to be crystal clear. The only downfall for me is that the filter doesn't allow me to shut the lid completely, but am thinking of upgrading their tank to the 2.5 mini-glass anyway. But overall, I highly recommend this filter. If you think your water is clear now, just wait until you put this filter in! It brings a whole new meaning to "clear water.!""

Nice!!!
Date: July 25, 2008
"I am currently using this on my 2.5 gallon tank and it keeps the water really clear & clean. The first filter pad lasted about a week before it needed to be replaced but that's because my water was really dirty even though I kept changing it. So I suggest buying the filter replacement pads as well, but other than that, I'm really happy with it. It is really quiet too, which is nice."

"The filter was a great price, my only issue with it is that when it is set on high water flow, the water comes out over both sides and over the top of the filter so i had to adjust it to a lower flow. The water is not as clear as i would like it."

Not a wise purchase...
Date: June 9, 2008
"I bought one of these about a month ago for my 2.5 gallon, and the first thing I noticed when I tried to hang it on, it barely fit around the rim (and this a 2.5 gallon that looks like a mini 10 gallon). Not only that, but the filter took a while to prime, and vibrated excessively. It sounded a pencil sharpener, and I needed to adjust it and tighten its grip onto the aquarium to prevent too much loud vibration. Then, once primed, it wouldn't stop making struggling noises until I put the filter on max power. Other complaints include that there isn't any beneficial bacteria growth whatsoever and the filter pads get dirty, fast. Also, the water overflows and completely misses the pads, going out the left side of the filter instead of the right, whenever its lid is on... Which creates a lot of annoying, bubbly bypass. All in all, I wouldn't recommend this thing to anyone... maybe I just got a bad copy, but who knows."

VERY GOOD PURCHASE
Date: May 30, 2008
"I just bought this filter because it had a very good reveiw. I am proud that i did it keeps my 1.5 gallon tank crystal clear. I bought my first fish a couple of months ago. I purchased a beta, and with the fish i bought a tetra water wonders 1.5 gallon tank kit. I just want to say it is a great kit to get started with. I was given a unwanted goldfish, and it was not well taken care of! Since my tank is square and the tank i was given is rounded at the top, I switched my original aerator filter with the nano filter. I love the way it cleans the water so good. It has virtually no set up, uses little electricity, it has a water flow set up, and it has a shiny look. YOU SHOULD BUY!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

Great for 2.5 gallon
Date: May 2, 2008
"Use this with my 2.5 gallon minibow. Stable little filter, quiet with adjustable current and betta has no problem with it - I only put a little silk plant near the intake and he has fun swimming around all over the place. He seems to like a bit of current to swim through."

Love it!
Date: January 26, 2008
"Before buying this product, I looked everywhere for a small filter that would fit my 2 gallon tank. I was so happy when I found this one!
I agree with the other reviews -- the motor is almost silent, and it's a very powerful and efficient filtration system.
One thing I recommend: Add some small ceramic filter rings to encourage even more bacteria growth. When you insert the filter pads, there's some space between the black foam and the plastic wall. I filled up the space with the ceramic rings, and just rinse them every month when I do my major tank cleaning/filter pad replacement."

Great Filter, just modify for Bettas
Date: January 8, 2008
"Filter works great. I modified it for my Betta b/c the current was too strong in 2.5 gallon. I took the end of pair of nylons and put it over the end of the tube part with rubber band so fins don't get caught. Then on top where waterfall comes out, I took a piece of plastic from an aquarium divider (has small holes in it) and put under where water comes out. Put it under the filter to secure it. If you curl it up almost like a cup it works really well. Calms down the current a lot. You have to trim the plastic where the tube comes out. If you experiment it works well. I used two pieces to get a wider coverage. In a 5 gallon you might not have to control the current but should still do the nylons so fins don't get caught up in the tube. A little extra work but they are worth it! This filter worked well in my 5 gal. also (with 1 Betta). Cleared the water quickly when my other filter broke."

Have gone through 2 of these
Date: December 18, 2007
"Wow, with all these positive reviews, not sure where mine will stand.
I have purchased 2 of these for my 1 gallon nano.... Seemed to work really well, when it was working. Then, they both just stopped... I took the first one back, got an exchange after working for 2 weeks. The 2nd one stopped after 3 weeks. Not sure if I should buy another one of these or not.
My experience has not been good with this one..."

Awesome filter!
Date: October 10, 2007
"I've had troubles in the past with submersible filters. I have been using this in-tank filter with my mini bow 2.5 gallon tank. Fits perfectly on the hood and it's very quiet! Gets the job done! Plus the filter replacement pads are almost always on the shelves at Petco stores.
By the way, my bettas like the filter too..."

Great Filter, Great Price
Date: August 9, 2007
"After doing research on this website for a good small aquarium filter, I decided to try this one. I am so pleased with it. I have a 2.5 gal aquarium with one Platy and one Dwarf African Frog. The Platy is a pig, always pooping probably because I inadvertently overfeed. He's always stealing the frog's food! The Nano filter is super quiet, you really can't hear it at all when you have the water flow set to low. It keeps the water crystal clear for at least a week and a half and then I do a partial water change. That usually produces a cloud of stuff that the vacuum didn't get up but within an hour or so with the filter running on high - the water is clear again. I would highly recommend this filter for people with small aquariums. If it weren't for the Platy that makes a lot of waste, I'm sure I wouldn't have to do water changes as often. The replacement pads are very reasonably priced as well. Great investment!"

Very pleased
Date: July 22, 2007
"I purchased this filter for my 1.5 gallon tank that I am currently cycling. I am planning on getting a pair of dwarf frogs once the tank has been cycled. I have had the filter for about 3 weeks now and it is great. It is virtually silent and all you can really hear is the relaxing sound of water being poured from the filter into the tank. It wont disturb you if it is in your room."

Great desktop filter!
Date: June 24, 2007
"I also have the 2.5 gal mini bow desktop aquarium.... mine houses an all-aquatic frog. I could not use the filter included with the tank because the frog requires a sand substrate and it just clogged up the filter... then I switched to a simple sponge filter supplied by the company that breeds the frogs, but these frogs produce so much waste, I was cleaning the tank more than once a week! Obviously, that's not good for the animal, but the water was so dirty and it smelled bad. So I went over to Petco and picked up this little filter and it has worked miracles!! Her tank is now incredibly clean - she's no longer swimming around in her own waste, molted skin, uneaten food or unfertilized eggs anymore! I like the adjustable water flow and the clear casing. I agree that the directions were a little lacking, but the pictures on the box make it easy enough to figure out... So glad I found this filter - and so is my frog!"

Best Small Tank Filter Ever!
Date: June 5, 2007
"I bought the 2.5 gallon mini bow aquarium and really didn't like the Whisper filter that came with it, so instead I bought this filter, and it's a lifesaver! It fits perfectly and I'm so happy because it's adjustable so instead of making my bettas tank have tsunami strong waves, now he can have the perfect amount of water flow. It's so small and yet so compact and powerful! Although there is a lack of directions, if you use a little thought it's easy to put together! Me and my betta Prince thank Red Sea Deco Art for making such a great little filter!"

Excellent!!!
Date: April 22, 2007
"About 4 months ago we bought a 2.5 gallon tank kit. The tank came with a in tank whisper filter that wasn't doing a good job filtering the water (the water was loaded with debri). Just a week ago I received the Red Sea Deco Art Nano Filter and hooked it up. Within 2 hours the water was crystal clear. The only fish in the tank is a male Betta. He had a case of fin rot due to water quality and the very next tank his fins started looking better. I HIGHLY recommend this product."
