Help Fixing a cracked tank
 

So I've got a standard 36" 50gallon
It was gonna be used for a sump
the back pane cracked
The crack runs horizontal in the middle of the back pane
The crack goes almost end to end
The cracked pane also has 2 holes drilled in it

Is it possible to just get a new back piece cut,
and just silicone it in, Ontop of the cracked pane, on the inside?

Or does the cracked pane have to be removed, then replaced?

Saver if you cut it out. Replacing a panel isn't that hard. I just cracked my sump tonight. Took me about 15 mins to cut out. And I'll order a panel from a local glass shop.

Hammers work wonders for removing cracked glass haha, just watch where you tap it and don't cut yourself

cracked glass
 

if you can save any of the broken glass a glass company will cut it for free(action glass will on edmonds);then use the cut pieces for your sump baffles.you can also order in newflex 333 aquarium silicone from them

good to know, thanks!
