The K Box system is a series of tubs, each of which is fitted with a conical overflow pipe towards one end. The boxes can be stacked so that the overflow of one is at the opposite end to the one below. |

The K Box Cone serves as the overflow pipe. The height of the Cone can be easily modified for a variety of tubs and applications. The Cone is attached to the base of the tub. |

The principle is simple - introduce water into the top tub, and it will overflow through the Cone into the tub below, and so on, down the stack. The cascade effect assists with aeration and reduces the chances of stagnant areas. Water that has passed through the stack can be recirculated, or filtered and then re-circulated, or put to waste. |

The basic principle can be applied to stacks of tubs of any safe height. In this example there are three stacks, each of four tubs, holding a variety of aquatic animals. |

The beauty of the system is that you can remove any number of tubs, and the system remains fully functional. Because of the simple overflow pipes, the plumbing is built-in and the system continues to deliver the same quantity of water to each tub as before. |

What are the K Box advantages?
- Simple assembly
- Can be quickly put up or taken down by one person.
- Simple plumbing
- All you need is a water supply and a collector tank, and the system remains fully functional even when you add or remove tubs.
- Self-supporting
- Does not need racks or shelves if stacking tubs are used.
- Flexible
- Tubs can be added whenever needed, and then removed as you use your product.
- Space efficient
- Multiple layers best utilise the available floor space.
- Water efficient
- Avoids a layer of under-utilised water present with deeper tanks so there is no need to crowd live animals on top of each other.
- Water quality
- Cascading water raises oxygen levels and reduces the chances of stagnation.
- Adaptable
- Can be used with flow-through to waste, or recirculation with or without filtration.
- Product separation
- Allows easy identification of batches of product.
- Easy storage
