Coralife Biocube 14 Gallon Review

If you are looking into getting a coralife biocube, this review may give you a better idea on what to expect. I am going to go into detail about the important aspects of this saltwater all-in-one system. This is my Coralife Biocube 14 gallon review.


The price of a coralife biocube is fair in regards to what it brings. What you are paying for, is an all-in-one system which includes:

  • Tank
  • Hood
  • Lights (power compact and LED light bar)
  • Return Pump
  • Integrated wet/dry biological filtration.

You really don’t need to buy anything else (except for sand, rocks, and fish) to get started. Most people spend extra money to mod their biocubes to an extreme, but it is not entirely needed as there have been many nano reef keepers who have successfully kept coralife biocubes with stock items.

Amazon normally has the best price for the Coralife BioCube 14 gallon with FREE shipping.


The design is definitely one of the best features about the system. With a sleek black modern look, the coralife biocube will look good in any room. Slightly smaller than the 29 gallon biocube, the 14 gallon biocube can fit into smaller areas of a room.

If you really want to go the extra mile, get the Coralife BioCube aquarium stand! It makes the tank look twice as nice.

Lighting – Ability to Grow Corals

Everyone always asks… “What kind of corals can I grow with the stock biocube lights?”. So to answer that question, I will be brief. You can grow most soft corals, some LPS corals, and a few SPS corals that do not require extreme lighting. The blue LED’s that come with the coralife biocube are mainly for viewing at night and to give the corals that extra ‘pop’ that we all want to see. The lights are not powerful enough to grow every type of coral you see at the fish store. But there are a few retrofit options out there to help implement powerful lighting to grow all types of corals right in the space of the hood. That’s if you can spare the extra change for the upgrade.


The coralife biocube comes with 3 chambers in the back of the system which are made to filter your water effectively. In the first chamber, you can leave empty or place a submersible water heater. In the second chamber you can use the stock bioballs which are used to create a wet/dry filtration system or you can run filter media which may include filter floss, carbon, chemi pure elite, chemi pure blue, and/or purigen. Those are just some of the more common types of filter media, but you can run whatever you’d like. There are plenty of options. You just need to determine what needs your tank has. The coralife biocube comes with a filter cartridge, so you wont be needing anything the first couple of weeks that you have your biocube running, but afterwards, you will need to purchase your extra filter media that will be needed.

Needed Add-ons and Accessories

Like I said before, this is an all-in-one system, so you won’t really be needing any add-ons. However, if you have a little extra cash available, you can buy items to make your system run better and to make your life a little easier.

Fish for Biocube

Being only 14 gallons, you are going to want to keep the amount of fish in the tank to a minimum. I would add no more than 2 or 3 fish to this tank. Clownfish, certain wrasses, and small gobies are good fish to keep in coralife biocubes.


  • Sleek design
  • Good lighting for soft and LPS corals (compact fluorescent lamps should be changed every 6 months)
  • Great size for any room
  • Can be used as a quarantine tank later on if you ever decide to upgrade your tank size


  • Can’t grow SPS coral very well with the basic lighting
  • Will need to do a lot of water changes or invest in a protein skimmer
  • Can sometimes cause your water to overheat due to the lighting and pumps
  • Back compartments are small, so they are hard to clean

    • Hey Beth,
      I would do no more than 3-4 small fish. I would stick with small clowns, wrasses, gobies, and maybe shrimps.

    • Hello Jason,
      I am unsure of this as I have not tried this. I also tried looking online and there are no answers. Please let us know if you find out the answer.
