Sorry to hear about your lose Chin.

No worries about the glass....... still looking for the 1/2 inch so I have not ordered it. But if you decide not to do through with the tank build........ that's cool also.

Cheers,
Vic

Oh man Chin, that sucks. imo the H2S thing sounds like a shot in the dark but really may be it. Did you get the smell of rotten eggs at all? if so, H2S; if not, start looking in another direction I find it really odd that the deaths were localized... check for mechanical problems like equipment. Do the fish have any signs of physical trauma other than flared gills? again, my condolences, hope the rest pull through.

something rotten got stuck inside your pump causing it ti spew poisonous hydrogen sulfide into your sump. anyway hope you overcome this and carry on with your tank build.
