This is the first time seeing this thread and I have to say while I admire your determination and effort put forth building this tank, it scares the hell out of me. 2 seams in the middle of the tank and 4 seams on the bottom and tempered glass on all pieces. Aren't you afraid that one of those rocks will get knocked over from a digging cichlid and bump your tempered glass and shatter into a million little pieces and dump your tank water and all its contents on the floor? Regardless of my fears for you having to clean up 100 gallons of water and millions of pieces of glass your tank does look nice so I hope you the best.
Oh my, sorry if it scared you.. BoooHH }
Me not scared..
1- Tempered glass shatter when rock hits it; well, my rocks are stacked to hold strong in place, and we often underestimate the real resistance of things.. Once i tried cutting my glass panel not knowing it was tempered glass.. got out all my bodybuilder strength on that panel, tried cut, hit it to brake apart, smashed against floor.. and to this day that panel has nothing more than a few scratches.
2-Because it is made of 13 panels, it has a flexibility that most tanks don't have, and which ever floor/base table/tank itself - irregularity that occurs is often compensated by the flexibility of the tank.
3- BONUS proof; In the last 3 months we had two earthquakes in Montreal... If it survives earthquakes I think its safe to say; no more worries
