Ok some updates....
I have cleaned up the tank, braced the top with Euro bracing all the way around 40mm all in 6mm glass + a 40mmx40mm support on each brace, all the joints have a glass strip so it's sort of a triangle at each join. Got glass for an overflow and will build a box. Not sure what I'm going to do for a sump but I think i'll try to build a sump in the cabinet. Should I go with a Nano stream or CLS? Lighting will be 2 x T5's on reflectors, DSB intank and sump will have Macro Algae..
Any other ideas?
