For divers who aren't as lucky to live in a nice hot climate with coral reefs the winter is a boring period. Even without corals, diving in Belgium in summer offers a lot of options with the North Sea, old quarry's and lakes full of life. But in winter time it's dark, cold and dead.
Luckily some inventive divers started with Todi, an indoor dive center in a water tank of an old cole mine. They filled it up with nice hot water, build a filter system and put it full with fresh water fish from all over the world. We visited the dive center earlier this year with my dive club and afterwards I made this compilation.
