Hi guys, its the local home swimming pool attendant responding to your kind replies and questions. Firstly, re. the glass thickness of 10mm (I've since found out,and not 12mm) which is roughly 1/2" for you imperialists out there, you would expect that Clearseal being the largest supplier of aquariums in the UK would know the correct thickness!?!. In regard to liability, the small print on their guarantees is exhaustive and basically allows them to cop out of anything according to the LFS manager who set up the system and in respect of torts, I may be the one sued on that basis for a tort of nuisance!!! (foul smell eminating from local house!) as I have barely been able to ventilate the property due to the worst torrential rain for a long time! (and thats something given the UK winters). As for the stand it is not to blame as it was the seals that appeared to come unstuck (maybe due to glass flexing but who knows)and this stand is 50mm heavy gauge steel and stronger than any stand I have ever seen, perfectly straight and made solely for this tank. The reason companies insist on their own stands are purely financial as they make a fortune on them. No, both of us were out, thank god or else we would be in hospital or dead thats why I mentioned about those of you placing your seating in a wise position, just in case!. The irony of all this is that I recently took a few fish out of this tank after taking the advice of the Tang brigade amongst you and these were my least suitable fish, now they are the sole survivors! how's that for fate?
