I know the bottom pane is tempered.
And I have no clue how to test if the side panes are tempered as well?
The time is drawing near when I convert my 55g into a DIY sump for the 125 I am running fallow...
I was under the impression all Perfecto 125's are tempered all the way around. But the reviews of possible failures of HOTB overflows vs drilled has me needing to investigate again, and I'm turning here, to r2r experience and knowledge.
I've heard of a "Sunglass" test, but I need an explanation, or some reinforcement...
Also, lets say I come to find out it is, in fact, NOT tempered on the sides and I CAN drill it... Would I have to empty the tank completely or could I just drop the water level down like 6 inches? (Enough to drill and catch any glass pieces/shards that fall from the hole as I drill it)
Help?
