Thats what i was thinking when they told me the price....they had a delivery of custom tanks that day aswell and the build quality looked realy good.
At first i was a litle concerned about the 6mm sides but the man re-assured me it would be fine as they have a sum out the back of the shop which is 60 x 12 x 15 made from all 6mm and its been there for a few years an is perfectly fine.
Ive sold me 20gallon tropical tank to my sister which is gd so will eb shutting it down during the week and giving it to her friday to make some room then all i have to do is move the marine tank to another room an ime ready for the big tank.
