Just curious, are most Concept tanks still euro-braced or are they like Red Sea, Elos, Wavebox which are not. Also, saw Bill Wan guy stating you should maybe consider triple plumbing overflow protection and use the highest quality of valves with unions ( Legend, Hayward, etc ). Do Concept tanks have this?
