Building a monster aquarium 700gal (Unedited)

building the monster aquarium for the new tropical fish shop which measures 2.9m2 x 1.2 x 700 mm and will hold 700 gallon or 3500 litres including the sump. This video is unedited due to lack of technical knowledge lol. The main challenge building this aquarium was the temperature been so cold and the silicone not wanting to come out the tube, please watch other videos on how we are converting a poly tunnel into a magical fish emporium.
Special thanks to Dan, Darren & Chris for helping
