2. Coralife LED Biocube Aquarium – Best 30 Gallon LED Fish Tank

The ornamental decorations and the glittery body of fish inside the aquarium look even more mesmerizing under colorful lightings.  Lightings are quite important to an underwater ecosystem, but excessive and long exposures could be equally harmful. Too little to too much illumination could lead to infestations.

Biocube Aquarium by Coralife is one all-inclusive aquarium that comes with nature-loving LED lighting fixtures. The LEDs are vibrant and color-enhancing, thus illuminating the insides of the aquarium sufficiently so that you can keep an eye on the health and upkeep of your fish tank all the time.

The LEDs inside Biocube Aquarium are bright white, sparkling blue and color-enhancing Beautymax lights that mimic the lightings of nature. The white LED lights are for daytime, sparkling blue moonlight glows at night, and the color-enhancing ones are to maximize the beauty of the overall aquarium set-up.

The soft glow of these LED lights helps to maintain the circadian rhythms of your fish because a consistent sleep-wake cycle is as important for the fish as it is for humans.

The timers are set to 30-min intervals of sunrise and sunset, and 60-min of moonrise and moonset and Coralife aquariums also come with a 24-hour timer, which is paramount for any fish tank with light fixtures.

As an aquarist, you might already know, that 24/7 illumination is unnecessary and harmful to the aquatic lives. Fish may become stressed after months of continuous exposure to sunlight or any other form of light, and tanks may show signs of algae infestations.

So why not fix the number of hours of illumination and darkness in your tank? Timers will help you to do just that. You can fix the time or hours of brightness and dimness that you desire, and this gadget will take care of it for you.

Buying Guide For Best 30 Gallon Fish Tanks

An aquarium is a sanctuary for your pet fish, therefore it is of utmost importance that you choose one which comes with the right fixtures to give your pet comfort.

The first two things you should be looking for are its lighting fixtures and filter mechanism—these two go hand-in-hand in keeping your fish tank clean and healthy.

And of course, ask your pet store-keeper the source of water in his store fish tanks and aqua-terrariums, so as to detect any possibility of worm or snail infestation.

A well-informed decision is a wise one because once you have bought a fish-tank as large as a 30-gallon one, and end up not liking it, returning it would be a cumbersome process.

Without further ado, let’s take a quick look at some of the factors that you should keep in mind before purchasing a 30-gallon fish tank.

1. Placement, Weight And Lighting

If the tank is a small one, you would not have to battle for space. Just keep it in one corner of the living room or dining space, and it looks awesome. Problems arise with large fish tanks, such as the ones as big as 30-gallons.

Aquariums are usually rectangular cases, seldom square or trapeziums. In case of the usual rectangular ones, you might like to place them in a corner, with some empty space left behind that could house the filter and wirings. Or you could place them parallel against the wall, in which case, it would take up sufficient space.

Therefore, before buying a 30-gallon fish tank, think about the exact location where you could place the large fish tank, and also analyze whether the fish tank would look chic when placed there. Take others’ opinions if you have to, but do not get compelled to purchase a big tank and then regret your decision.

Another factor you can take into consideration is the weight of the fish tank. A 30-gallon fish tank may weigh anywhere between 20 and 80 lbs, but it also depends upon the material the exterior is made up with.

Aquariums made of glass with metallic frames might be quite heavy. If you are looking to ship the product from another country, for example, you should better consider an acrylic-made product.

Though highly impact-resistant glass aquariums are available these days, acrylic is unbreakable and weighs half as much as glass products. Less weight means your shipping charges would fall dramatically low as well.

Also, consider the lighting fixtures that come with the fish tank or the ones you would be purchasing separately for your tank. LED or fluorescent lights that come in the package of the product, do not require that much of a hassle to set up since they are already compatible with the fish tank.

Problems arise when you are willing to customize and purchase lightings not enclosed in the package. Check the hood or the cover of the aquarium and ask does it give you enough independence and convenience to fix the lightings.

Do the hoods have transparent windows through which light would be able to penetrate the aquarium? Also pay attention to the mechanisms that would hoist, clip or hold the lights up, in different angles, to create that ambiance you are aiming for.

2. Size

There are 30-gallon tanks and 30-gallon breeder tanks that might slightly vary in size. 30-gallon aquariums are usually within the dimensions of 36¼” x 125/8” x 163/4”, whereas 30-gallon breeder tanks are within 363/16” x 18¼” x 1215/16”.

30-gallon tanks could best be described as mid-sized tanks since they are larger than nano tanks and smaller than giant tanks. As such, they are easier to clean than the larger tanks.

Water change is faster, filtration is easier, and possibilities of algae, worm or snail infestations are much lower. Therefore, going for a 30-gallon fish tank, is a wise decision, especially for beginners who have some practice at maintaining fish tanks.

3. Material

As mentioned earlier, depending upon the environment of your house and where you are shipping the product from, among other factors, choose the aquarium that is best for you.

One of the most important features in the best 30 gallon fish tanks would be the material they are made up of. Two good options are available for you—glass and acrylic. Let’s look at each separately.

Glass: In traditional fish tanks, the exterior is usually made of glass. Glass tanks are scratch-resistant, a much-sought-after feature of this material. Look around where you want to place your glass aquarium. Even if there are steel or metallic objects nearby, or things with sharp edges, you can be assured that they would not be able to leave any scratch on your glassy, shimmery aquarium.

Also, glass fish tanks have rigid panels, meaning they are more durable. Glass is also super-transparent, a most-wanted feature when you want to have a clearer look at the happenings inside the tank, or want the tank to be a source of pleasure for your friends and family.

Additionally, glass does not accumulate stain over time and is easier to clean. Also, glass is non-porous, meaning they do not leak and unwanted things cannot get inside the tank. They are quite cheap as well.


Acrylic: These days, acrylic is a reliable alternative option, if the glass product is not to your liking. If you want your fish tank to survive rough man-handling during shipments, and remain in one piece when it reaches your doorstep, you can consider the acrylic option.

Acrylic construction also makes the aquarium more-lightweight, therefore much easier to move around, and is not that highly dependent on a stand or a cabinet.

Cabinets are quite useful nevertheless since they offer storage space for fish tank materials, like gravel and fish food, but acrylic tanks, being light in weight, can be placed on simply any stand. They do not require a specially designed stand to go with it.

Another benefit is that acrylic-aquariums could also exist in a variety of shapes—not just the regular rectangular version. Acrylic aqua-terrariums could exist in cylindrical, round, and hexagonal shapes!

Also, as previously mentioned, the properties of acrylic make it 17 times more impact-resistant than glass.


1. How do you set up a 30 gallon fish tank?

Ans: At first clean, the fish tank thoroughly, because you never know its surface might be carrying unsightly algae and worm eggs. Then you should consider its placement or positioning.

If you have some experience taking care of fish and aquariums, then you might already have a separate place where you keep all your fish tanks. But if you are planning to keep the fish tank in a place where everybody could see and enjoy the view it has to offer, then consider a clean and dry corner or wall, and make sure the spot is away from windows, and wirings or plugs.

Then add the gravel, water and filter, and see if everything functions properly. Wash all decorations and plants with old tank water before adding them into the new tank. After decoration, run a complete nitrogen cycle with or without the fish in it.

2. How to maintain a 30gallon fish tank?

Ans: With nano-tanks and larger tanks, there is a higher possibility of algae or worm infestations, since water gets dirty quicker, though it depends on how rigorously you maintain your fish tank.

Mid-sized tanks like the 30-gallon ones, do not require such regular upkeeps and can clean themselves pretty well. 30-gallon tanks usually come with the 3-stage filtration mechanism with cartridges included in the package.

This 3-stage filtration—mechanical, chemical and biological filtering, ensures your tanks stay clean and healthy.

Remember to not feed too much and too frequently, and before adding any decoration, wash them first in old-tank water. Do not wash anything with chlorine, tap water or detergents.

3. What is a brackish fish tank?

Ans: Fish tanks that have both fresh and salty sea-water in combination are called brackish fish tanks. These tanks support special categories of fish—like puffers, for example. Water change and tank maintenance is super cumbersome, so these types of tanks are better left to the specialists.


Final Word

If you are thinking of purchasing a bigger fish tank to shift your fish to a bigger house, no need to look any further. If you are well-experienced, you can go for large, super-nova fish tanks, but the scenario is slightly different for enthusiasts or beginners.

Mid-sized tanks are great for beginners, who have only a few months or a few years of fish-keeping experience. 30-gallon tanks are perfect mid-sized fish tanks. So what are the features you should look for in the best 30 gallon fish tank?

Consider the size and weight first. Are they too big to fit the corner you have chosen in your house to place the 30-gallon tank in? Whichever corner you have chosen, leave some space free at the back to the house the filter, because filters are essential for healthy upkeep of mid-sized tanks.

Glass and acrylic builds are available. Glass is a tad heavier than acrylic versions. But glass is also more stain-resistant and clearer than acrylic constructions.

Manufacturers today have made available myriads of options for the consumers to choose from. Some of the best ones include SeaClear, Fluval, Marineland, Aqueon, R&J, Coralife and Aqua Culture fish tanks, to name a few.

Take a leap of faith and give your fish a bigger house to live in! The proper upkeep of your tank will help build a stronger bond between you and your fish buddies.
