These ~fintastic~ decorations, plants, and accessories are going to transform your fish's tank into an underwater paradise.
Promising review: "Does a fantastic job cleaning the algae — even old stubborn build-up growth — off the inside of my glass aquarium. Works even better than I expected, and the felt pad on the bit that's in contact with the outside of the glass does a decent job cleaning off any water spots and finger/hand-prints. Also, I have degenerative osteoarthritis, peripheral and small-fiber neuropathy, and hEDS (among other issues), all of which make it very difficult for me to do much of anything with my hands. I wasn't sure if I'd be able to use this thingy, but it was a lot less difficult than I thought it would be." —Franklin

Air pump that causes the bubbles is not included.
Promising review: "My kids love bubbles, and the idea of micro bubbles intrigued me. Decided to give it a try since I have a tank without a bubbler/air stone. I ended up soaking it overnight (my day got busy before I could mess with my tanks), and I finally dropped it in today. The stone is awesome. It is ridiculously HEAVY, so it stays put once you have it where you would like it. It came with suction cups to route the tubing, but I didn’t need to use those (yet). The micro bubbles are quite mesmerizing to watch. But it’s like watching cigar smoke dance through the air the way the bubbles dance on their way up. I may need a second or third stone and use them as decor. Also, make sure the stone is under the water before you turn it on, otherwise you will get a wet surprise! I did soak mine in a dish of tank water before use, not water from the tap." –MamaOf4

Promising review: "I have a 20 gallon tank that I wanted some taller plants for. I rinsed them as per usual with new plants. Put them in the tank and I have to say they look beautiful and my gouramis love swimming in and out of them. They have a sturdy bottom on the so they will stay where I put them and I think they will be easy to clean. Super happy with my purchase and will do business with this company again." –Franci

Promising review: "Fantastic product, good suction easy to use, small footprint and love the pistol grip. Gets under decorations between plants and in corners. Easy peasy and clean up is a breeze. I LOVE IT SO MUCH I'm getting another for the fish tank at my Mom's house. This hose would be overkill for 20 gals or less but I have 40 gal tanks.The trigger can be pulled on and off and it shakes the gravel for you. You won't go wrong with this product." –Carrol

Promising review: "The quality of this log is outstanding. Not only is the detailing gorgeous but it also doesn’t have jagged edges on any of its entrances, making it safe for long finned fish like bettas to play in. My fish loves his log and uses all of the entrances. Would buy again!" –Mina

Promising review: "This is THE best stuff ever. My fish LOVE it and it lowers their stress so much so their colors came back and they look so much happier. I have cichlids and color is very important to defining if they are stressed out or not. I have used many pet store recommended (just because they are expensive) water conditioners that aren't even scratching the surface to how much I love this water conditioner." –Cheyenne

Promising review: "I have this on a 60-gallon aquarium and so far it's working great! It's easy to program, holds a lot of food, and is easy to adjust how much food you want to dispense. So far I have only used flake food in it, but it's handling it just fine. I can't speak to the battery life because I've only had it on for a few weeks, but so far it still shows full battery life. I decided to use it as the everyday feeder, and not just when I'm out of town. I like to keep consistency with the tank." –Steve - Broadcast Engineer

Promising review: "We absolutely love this product! We have been looking for fish tank ornaments that would glow, and some have seemed rather static. This one is made up of a gummy-like material and we have put it in the center of our tank where the filter stream moves its tentacles. I find myself often just sitting and enjoying it’s movement just as I would the movement of the fish." –Allison Reed

Promising review: "I’m really happy with the performance of this filter. It works very well. I’ve had a larger one of these for the last two years and had worked wonderfully in my 54-gallon tank. That’s why I decided on this one for my 20-gallon tank. I noticed a big positive difference in my fish’s behavior and demeanor. My previous filter was pretty sub par and this filter has really perked up my fish." –Piano trying to be a guitar

Promising review: "I have had this product for over three months and every day someone walks into my office and asks where did I get my jellyfish and that they are the coolest things ever. Every single one of my office mates have asked if they are real. My fish love them and swim around them all the time and love playing tag through them. Best purchase I have ever made. My fish tank looks killer. Definitely recommend." –Coral Owens

Promising review: "Don't force yourself to look at a boring bare bottom tank! This is perfect for fish to forage through, especially goldfish, and is really beautiful to look at. Did I mention this brand won’t annoyingly be sucked up by your siphon?" –Jennifer

Promising review: "What a great addition to my tank without even touching the water! I didn't want to keep my fish bathed in colored light but I like the color changing so this is an awesome alternative. I put it in back of the tank on the table and it makes for an awesome effect. The fish don't seem traumatized by the colored light. It creates a neat effect for the room too. The price was just right. It doesn't get any better!" –Elle B.

Promising review: "These are pretty good pumps for the money. They are quiet, and surprisingly powerful. I use this one to drive a double stacked sponge rated for around 100 gallons, and it does really well. I also have a smaller version of this running a small sponge filter on my 10-gallon, and it does a good job. Overall these are inexpensive and work well. I would recommend." –Amazon Customer
