Coralife Biocube – Between the Line Analysis

Coralife Biocube comes in various sizes. The 29 gallon model is an easy-to-handle tank for the newbies. This all-in-one system weighs around 53.1 pounds and combines all the key features of a coral-reef tank including a light filter, a filter pump, a sump tank LED light bulbs and many more. The newly enhanced models have gone through some improvisations on performance and overall function.

The contemporary hinge-top canopy design contains a four-button control system and separate bars for daylight, actinic and LED bulbs. The upgraded cooling system is a nice, little addition to maintain a right temperature of the unit. The most unique part of the tank, however, is the 3 rear chambers. The middle chamber is a vast refugium. It is the place where living organisms live and grow algae. This chamber has visible glass back panel, meant for placing LED bulbs with the help of suction cups. Chamber one holds a heater and a filter bag of phoslock. The last chamber contains the water pump.

The excellent filter system with attached cooling fans does its job without making disturbing grunting noises. The submersible pump has a stellar flow rate of 180 gph, resulting in better water circulation and filter performance. Modular LEDs added in the aquarium not only highlight the stunning, vibrant colour of corals, but also help in growing SPS, LPS and seldom, soft corals. If you wish to experiment a step further with lighting, purchase additional LED retrofit kits to bedeck the hood of the tank.

Although it’s an all-incorporated aquarium kit, if you have extra cash in hand, I’d recommend to buy a couple of additional equipment like a protein skimmer, basically used for sieving out fish droppings and uneaten foods from the water. The sump tank, located beneath the main glass display, improves the water volume. Get a UV sterilizer to take out excess algae from the water .after all the preparation is done, start making layers of live rocks and live sand. Then pour the water and start the tank! Please make note, before putting fishes in the tank, cycle the water for about a week.


  • Compact, well-built, has 3 separate chambers to store different parts of the tank.
  • In the second chamber, you can use stock bioballs to create wet or dry filtration system, according to your preference.
  • Hinge-top canopy design.
  • Adding accessories is convenient, thanks to the easily removable top.
  • Back chamber for fitting protein skimmer and filter floss.


  • Some reviewers have complained that the lighting system turns heated despite the cooling system.
  • Hard to clean the back chambers.

My View

Coralife Biocube is an awesome fish tank to experiment with if you lack prior acquaintance with reef tanks. Equipped with excellent decor, minimalist design and enviable features, Coralife has once again proved its mettle. Even though the product costs slightly higher than most of the run-of-the-mill aquariums you’ll find in the market, but that has hardly ever affected the market value of Biocube fish tanks.
