Coralife Biocube 32 Overview

Coming at a very favorable price point, the Coralife Biocube 32 reef tank is quite attractive to people just getting into saltwater tanks. This tank is built to give everyone enough space to work with but not overwhelm them. 

Coralife Biocube 32 Review Overview

It’s quite collected as a tank and does a great job teaching only what you need to know, with no additional problems if you’re just getting introduced to saltwater fish. Now you can set it up as a freshwater aquarium. However, the best way to utilize it and show its best is as a saltwater aquarium.

What’s Included in the Box?

The Coralife Biocube 32 gallons is packed quite nicely, and everything is nice and well-built. Inside the box, you get:

  • the tank itself, 
  • the filter, 
  • filter chamber, 
  • the pump,
  • and the LED lights. 

All of these are included in the box with no additional payment. We weren’t kidding when we said this is an all-in-one fish tank. Everything you see is custom-made and high quality, meaning you don’t have to go shopping for accessories too besides a stand, of course. We’ll catch on to that later.

Set up and Maintenance

The Coralife Biocube 32 setup is pretty straightforward. You get the things out of the box, remove the protective styrofoam, and everything after that is pretty much self-explanatory. You can focus on the inside when you’re done with the outside.

Now it’s important to leave enough space for the fish to swim around and leave some cracks to go through like they normally would. After arranging the interiors, you can then add the saltwater. The water will probably cloud; no need to worry, it’ll clear soon enough. It’s recommended to wait for 1 to 2 hours before putting the fish. However, some people like to let everything work first for around a day to ensure everything is clean, filtered, and ready. 

When it comes to the Coralife Biocube 32 maintenance, there’s nothing special to keep in mind besides the usual checks and changes. This is one of the easiest tanks to set up and maintain so you won’t have any problems on either of those departments.

Key Features of Coralife Biocube 32 Reef Tank

The Coralife Biocube 32 seems like it was created to assist you in realizing your goal of having a tank, regardless of your previous experience. It’s not an easy task to find such an age-proof product that’s sure to last you years to come. There are several features that give this tank the name it has for itself, and we’re going to discuss them below.

Design and The Tank

This cube aquarium has an excellent and elegant appearance that appeals to any fish keeper. The cube’s hood and canopy style will add to the attractiveness of the side where you install it. It will show you three different perspectives. 

Because the tank’s filter is adjusted at the back of the tank, you don’t have to worry about that. As a result, you won’t even have to bother about the placement and adjustment of ornaments like plants, corals, or stones. It’s basically foul proof in design, and it can’t look good even if you actively try to make it look not good. It weighs around 62 pounds, it’s square and made of glass with black borders, and the dimensions of Coralife Biocube 32 are 27.5 x 25.5 x 27 inches.

Filtration System

Filters are a must-have for any fish tank. There are several alternatives out there, and without the proper research, you’ll feel like you’re never going to find the right one and end up making a random impulsive buy. Besides, purchasing a filter does not finish your task; you must also handle it well. With it comes a ton of upkeep, cleaning, and tweaking that must be done before you might even reconsider buying the tank at all.

However, you won’t have to worry since the Coralife BioCube 32 has its built-in filter that will eliminate making a choice altogether and provide a quality and compatible filter system for this tank.

You may personalize the filter by selecting a media type. It is compact, has dual intakes, and has a submersible pump. Also, it has an adjustable return nozzle, and you can thus control if or not the water cascades into the tank or trickle.

Lighting System

Such an amazing product undoubtedly doesn’t lack an equally amazing lightning system. The low-profile hood integrates luminous Cclor enhancing LED light capable of maintaining and growing otherworldly vibrant corals and plants full of life.

It also includes nothing short of a built-in 24-hour timer, making it easy to control the three independent light channels for maximal charm: bright white, sparkling blue, and color-enhancing LEDs.

Just when you thought nothing could top that off, this product goes off to combine automatic functions of 30-minute sunrise/sunset with 60-minute moonrise/moonset, to flawlessly replicate a natural cycle of day/night for your aquatic environment. We tested the lighting of the Coralife Bopcube 32 with Candy Cane Coral, and our coral thrives thanks to this powerful lighting system.

Temperature Control

I cannot stress enough how vital it is to keep your aquarium at the proper temperature. To have a healthy aquatic ecosystem, the water must be at the appropriate temperature. If the water is too cold or too hot, there will be consequences on your fish and reef to the point of losing them. 

There’s no doubt that Coralife fish tank has taken all of this into account. The user has complete temperature control with a temperature control system in this tank. For example, the water is often heated by the LED lights and is cooled by cooling fans inside the system. It all is indeed an amazing thing, finally giving your fish what they deserve and giving you peace of mind knowing your pets won’t freeze to death one day.

Coralife Biocube 32 as a Freshwater Tank

It would be simply extensive to go on and find any more reasons why we know for sure that this tank is just as good as a freshwater tank. No matter how specialized this tank is for saltwater, it does the job either way and won’t be a problem on both occasions. Follow proper freshwater aquarium maintenance tips to ensure your freshwater aquatic pet a happy home.

“You can be the juiciest, best peach on the tree, and there’s still going to be someone that just doesn’t like peaches”. If this is the case, don’t worry, you can modify this one “peach” to however you prefer.

Below you’ll find a list of products that will make your fish tank seem like you 3D printed it with the level of customization they enable.

Biocube 32 Light Upgrade

The lighting will need to be changed if you want to put corals with higher lighting requirements in your Biocube 32. This tank’s integrated LED illumination is excellent for soft corals and some LPS corals that require low light levels. As one of the tops LED lights for tanks.

The Kessil A160WE Tuna Blue LED can handle all sorts of corals and plants with no “side effects” to your fish or environment. Kessil is a safe bet. This light on the Coralife Biocube 32 looks fantastic, and the design is clean and contemporary. This light is enough to make you want to live in the aquarium yourself when you see how good it looks. Jokes aside, adding it to a Coralife Biocube 32 gallon tank is a great addition.

Coralife Biocube 32 Stand

On bigger tanks like this, it’s important to have a tank stand for them to sit on. By not finding the right stand, you risk your aquarium and whatever stand you put it on because coffee tables or TV stands aren’t made to withhold big weights like this. Even if this wasn’t the issue, the stand also plays an aesthetic role.

We highly doubt there is a better way to showcase your precious aquatic habitat than on a Coralife Designer Biocube Stand. Fresh and updated black panel for increased stability; no glue needed.

Best Protein Skimmer for Biocube 32

What better way to make a Coralife Biocube 32 upgrade than a Coralife product. A wonderful complement to any Coralife Biocube aquarium would be the Coralife Biocube Protein Skimmer. As they are particularly intended to fit into chamber 1 of the rear portion, they allow you to close the tank’s lid without modifying it.

You need to be clear on what you’re doing because it’s easy to misuse them. It takes time for them to break in and start operating correctly, just like any other skimmer. You may want to change the pump to a more powerful one during usage if you happen to have one lying around. If not, air pumps rated for 10 gallon fish tanks work well on this occasion. This skimmer won’t solve all your problems, but it’ll definitely solve one permanently.

Circulation Pump Upgrade

There’s nothing wrong with the pump that comes in the box. Actually, it’s pretty good. However, as we’ve mentioned all this time, everything is relevant to your situation. The Biocube 32 gallon tank’s return pump is rated at 264 gallons per hour (GPH). With an average tank turnover rate of eight.

Compact design

Your tank’s typical water turnover rate should be 20-30 times your tank’s water capacity. Depending on your setup, this may work for you if you only have just fish or soft corals. If you plan on putting something other than that that requires more flow, adding a wavemaker or aquarium powerhead to the Biocube 32 will increase the flow rate. 

The size of the return pump can also be changed to increase the flow. However, with the addition of a wavemaker, you’ll have additional choices for controlling the flow of water. Koralia Nano circulation pump will be the perfect choice to get a bit extra flow in your Coralife Biocube 32 tank. They are quite tiny and will increase your turnover rate to the desired level. If you get the 425 GPH model, putting everything above together will put you beyond the 20 times turnover rate you’re aiming for at 690 GPH.
