Looking after the water is a very important part of what we do here at The Deep.

GLIMPSE allows you to see behind the scenes, giving you views into areas of The Deep that were previously off limits. See some of the important aspects of aquatic engineering and get an insight into what it takes to care for our amazing species.

As you journey around The Deep, look out for the glass doors and take a peek into the plantrooms. If you see an Aquarist at work behind the scenes, be sure to give them a wave!

The view from the first window near the entrance turnstile looks down into our largest exhibit of over 2 million litres. Here you can also view our main diver entry where our team get kitted up each day to perform the daily dives at 2pm.

Intro plant room

Firstly what the heck is a plant room? This is the name given to a dedicated space or room that houses all the mechanical and electrical equipment required to keep an aquarium running. This includes water sumps, filtration, heaters, chillers, water pumps and Ultraviolet (UV) light – to name just a few!

Here in intro plant room we take a look at our surge generator that provides flow to our open topped lagoon exhibit that you will see as you make your way around.


Providing the right water movement is an important part of creating a natural underwater habitat. The correct flow of water is important for feeding and breeding, but it is also makes sure that there is a good supply of oxygen moving through the environment. This is essential for keeping the animals healthy.

How do we create flow in our lagoon exhibit?

We use three methods of generating flow in our lagoon system:

1. Water return flow - Water returning from the filtration system enters the exhibit through pipes in the rockwork. This flow is constant and in one direction only. This type of flow Is generated by large in line pumps, whose output can range from 0 to 250000L per hour

2. Propeller pump flow - Powerful propeller pumps generate flow within the actual exhibits to create areas of high water movement. By changing the pump programming we can create surges of differing intensity and frequency.

3. Vacuum driven surge device - This clever system uses a powerful air pump to suck water into a chamber next to the exhibit. Special pneumatic valves then alter the flow of air so the pump then pushes water out of the chamber. This cycle repeats every 3 to 4 seconds. The result is a mass movement of water that mimics the rise and fall of the water level in a shallow reef environment. This is good for fish health and the suspension of waste particles within the exhibit.

Did you know? Water flow is important for exercise, food distribution and providing oxygenated water.
