The Best Nano Reef Tanks (Review) in 2021

The design of this small reef tank alone is a clear indicator of the stellar features it has. So, this is certainly one of the few cases where you can judge a book by its cover. Best believe that the Hagen HG Fluval Flex Aquarium has quite the aesthetically pleasing cover. For the most part of it, it is made of glass and is equipped with a total of three viewing sides. What’s more, the front panel curves outwards and the result is the illusion that this 15-gallon tank is a lot bigger than it is.

There are red, blue, white and green LED lights fitted here and for convenience, they can be controlled using the Flexpad remote included. On a more functional level, the white 7500k LED lights are put in place to encourage plant growth. And the cherry on the top here is the 3-stage filtration system which uses an oversized mechanical, chemical and biological filter to ensure that the water is cleaned periodically.

It may be a bit on the cheap side, but who does not like a good deal? Even better is the fact that it offers up a lot more than what you’d expect for its price. Get ready to be pleasantly surprised as the top-notch qualities of the MarineLand Contour Glass Aquarium Kit are highlighted. First, take a peep at that design, not only is it stylish but it is downright eye-catching. The unit is fitted with curved glass corners that really let viewers into the lives of the fish and coral. All this and more is placed on an actual pedestal that really drives that stylishness through the roof.

With the bottom covered, it’s time to look upward at the transparent cover which actually slides in order to offer up easy access. All in all, this makes maintenance very easy and as a bonus, there’s a perfect aerial view of the aquatic habitat. A serious wow factor here is the light rail fitted with LEDs that hang over the tank itself. Not only is it a wonder to behold, but it also lights pt the tank for all the right reasons.

Here’s a tank with a little more in terms of capacity, so for anyone looking to have a more extensive aquatic family, this is a great route to take. With a capacity of 16 gallons and an array of other features, the Coralife LED Biocube Aquarium is a viable choice. Just looking at the overall design is a pleasure on its own. The sleek, modern style here will definitely fit into any setting effortlessly and it comes fitted with a total of three transparent sides which allow for an extensive view of the tank. Then there’s a hinged lid right at the top which offers even more access for feeding and upkeep purposes. Still, on the lid, there are LED lights embedded which solely come in white and sparkling blue.

Thanks to the colors available here and their brightness, this unit can be used as both a nano saltwater aquarium as well as a freshwater one. If that does not make for a stellar all in one nano reef tank then nothing else really does. A major selling point here is the 24-hour timer that controls the light setting on cue. Then, of course, there’s the detachable, dual compartment filter that supports both mechanical and biological filtration.

It may be small but best believe that it has all you need to create the perfect mini marine experience. It probably has the same features bigger tanks are equipped with and the added plus of being a lot more compact. Grace your countertop or desk with the Fluval 10531A1 SEA EVO XII Aquarium Kit and add a little splash of color to your world. Speaking of color, the bright 14000 K LEDs here come in an array of eye-catching colors. They also come with an easy to use touch start which further has day and night settings.

Even better is the fact that they go a long way to promote healthy marine life and there’s also the lid or canopy here which does not only act as an accessible feed door, but an avenue to get a better glimpse of bustling aquatic habitat within. A great addition to this mix is the heavy-duty 3-stage filtration with its accompanying over-sized media. This goes a long way to ensure that the water in the tank is pure and pristine.

As far as beginner nano reef tanks go, this is one of the best options out there. It has all the little tidbits and accessories included in the mix. As such, users don’t need to scramble around to get them. Think of the Marina LED Aquarium Kit as a nudge in the right direction. All the sides of this all-glass, cuboid tank are transparent and that allows for a more immersive experience altogether.

What’s more, the top is the only opaque attachment and is fitted with a daylight effect LED lighting module which enhances the natural feel and keeps all the aquatic life healthy. Additionally, the kit also contains essentials such as a water conditioner, a net, and even fish food. And there’s also a handy manual thrown in the mix to ensure that beginners really get all the hands-on information they need to succeed while the aquatic life within thrives.

If you are on the lookout for something ready to use, straight out of the box then this is definitely the route to take. There’s not much needed with the SCA 50 Gallon Starfire Glass Aquariums in terms of installation. It’s all a pretty straightforward process and there’s an even better experience waiting once it’s up and running. This rimless tank is as sturdy as they come and are equally fitted with two sturdy cabinet doors. Based on this alone, longevity is not a concern at all when it comes to this nano reef tank.

There’s also an array of accessories thrown into the mix, so that’s already quite convenient. And let’s not forget the skimmer, pumps, pipes, bulkhead tubing and so much more that are made available. The only thing you’ll have to get on your own is the lighting and when that is done, you’re good to go.

Here’s a cute little unit that’s simply perfect for anyone who’s trying to economize space. It’s small enough to conveniently sit on most flat surfaces without causing a disruption. Its size is not the only thing the Fluval 10528A1 Evo V Marine Aquarium Kit has going for it though; there’s an array of nifty features that complement it quite well. Before delving in, keep in mind the fact that this is a small saltwater tank and it creates quite an ideal environment for marine reefs. For this reason, it happens to be fitted with 11000K LED lights and among them is a blue light that vastly supports the growth of marine coral.

Design-wise, you’ll notice the cube-like shape and addition of three clear sides. The cover is equally transparent which makes for quite a viewing experience. As if that was not stylish enough, this tank is graced by a honeycomb design which is not just a pretty face. It equally conceals the filtration area making for a more natural look.
