The Elos rimless tank
Was the design that was 'stolen' by virtually everyone who makes rimless tanks now
But Elos used a special adhesive silicon. Thicker glass, and thicker silicone bonds
And shorter tank walls
Than those who copied them
And sold them at half the Elos price(Red Sea specifically)
Putting Elos out of business, essentially. I mean you can buy one now, but good luck
Red Sea also messed up on the structural integrity of their long tanks, and the long stands that went with them
Red Sea tanks previous were all heavily rimmed
