Too expensive for my blood untamed! But it would be nice.

I did check the nut i have crabs, and there were no rough edges, just a washer on the flange side.

walloutlet, my tank is definitely done when the plumbing is done!! I don't normally redo any plumbing unless it leaks. LOL I loathe plumbing.

I have always used some silicone on mine. Not on the gasket side though. I put some on the threaded side, which is the outside in my case usually. This gives me an extra seal on that side. I usually then put a bead around the outside of the gasket/bulkhead, after its been tightened. I have only ever hand tightened.

Agreed its a pain when one needs removing, but on a tank whens that?? Your sump is perhaps a different story though, but I would still do it the same if it was mine.

Never have had a leak that way in 25 yrs. So far.

That sucks, I would try using some silicone next time around.

Thin glass and bulkheads are tricky. To tight and snap. Silicone is your friend on smaller tanks. My 10g sump, I cracked the whole side too. I managed to silicone a glass patch cross the crack, and it has held up so far.

Sorry to hear about the crack but trying to understand how.

If the flange and the nut is fully supported by the glass (correct hole size for the bulkhead) and faces are smooth, would think when tightening, the plastic threads would strip before you could get enough compression to shatter the glass.

With really thin glass it's actually quite easy to crack it by over tightening the bulkhead.

I haven't decided what I'm going to do. right now I'm leaning towards just replacing the pane so I don't have to redo all the baffles. Or I might just build one from scratch so I can use better dimensions and get more gallons in there. I dunno, right now I'm trying to ignore it.

If there is any irregularities on the bulkehad flange, it can easilly overstress thin glass.

One more reason I love tempered glass. All my tanks and sumps are tempered.
Maybe consider going tempered on the next tank it is not that much more, 7x stronger and has flex to it.
They will drill the hole before they temper.
Tempered is like heat treated steel they heat it red hot to align the particles and then cool it rapidly with big fans. Think of it as the difference between mild steel and tool steel.
