Bert Roos is the proud owner of a beautiful North sea aquarium
The first idea could be that a North sea aquarium is colourless. The opposite is true.
The photograph shows that a North sea aquarium is very worth it. The water from the North sea is 10 up to 15 degrees celcius. The Aquarium water is kept on 14 degrees in the winter and 18 degrees in the summer. The aquarium volume is 400 litres. Lighting exists from 4 tl tubes of which 3 x osram, 36 Watt and 1 actinic 03 tube. Light in a North sea aquarium must be subdued.
