What is it like to swim with dolphins?

As you watch the dolphins at Marineland racing, jumping and playing, take a moment to observe the current in the pool. That current is there because of the large filtration system that helps clean the water.

We use ozone to maintain a high level of water quality for our marine mammals – eliminating the need for high residual chlorine levels. The advantage of ozone disinfection as compared to chlorine disinfection is multiple.

Ozone is a colourless gas that is formed by passing oxygen through an electric field. The rate and efficiency of ozone production is affected by many variables such as air flow, percent of oxygen in gas feed, dew point of gas feed, air pressure, cooling water temperature, voltage and frequency applied to electrodes.

Ozone is a more effective disinfectant than chlorine and removes viruses and lowers the colour and turbidity. Ozone also removes suspended solids. Unlike chlorine, ozone does not change the pH of the water, nor does it react with the remaining organics in the water.

Hey! Are you looking at me?

If you were to enter the water, one thing would become quite obvious to you. You would float much easier in this pool than you did in the lake this summer. These tanks are filled with salt water, about three per cent salt water. Whales and dolphins need salt water because it is denser than fresh water; therefore, it is easier for them to float and swim. The salt water is made right here at Marineland, simply by adding common table salt to fresh water.

Once you entered the water, you would undoubtedly notice that you are being watched! Dolphins are very inquisitive and usually very playful and friendly with humans. Under water, you would hear the chatter and whistle-like sounds of the dolphins. Also, you might hear and possibly feel the echolocation clicks as they explore you with their extra sense.
