Thanks Tony.
The 30G cube I currently have running is a 24x24x12 as well, and like you the water line is really 11-11.5" depending where you measure from. And yes, I have to be very careful cleaning the glass as the water likes to splash up over the sides, however the actual flow (Vortech mp20) never gets it so wild that in crests the rim of the tank.
With this tank I made a small adjustment with the dims and went 14.5" tall (glass dimension) and 12.5" water level giving me a full 2" of glass, which I am hoping will resolve the previous issue.
As for photos.... I should be ok.
Time will tell I suppose.
