Thank you for your valuable link. I'm not going insane after all.
Yes it was, I started with a 620T and it broke just b4 5pm so I quickly rang around to buy anther one, the shop that I bought it off said I would have to buy the whole kit not just the tank, I said no to that as it was going to cost me an extra $300 for the top which mine was in perfect condition. So I went to another retailer, when I went to pick it up he said he doesn't stock the T's as they have a tendency to break. I got the short one but they are in my opinion not as nice to look at, my fish were a bit squished with the less water to swim in as well. Then of course that broke and I got a third one off the importers, the gentleman that I spoke to was really nice and said he would reinforce it as I was ready to give up at this stage. At 6.30 am I woke up to the sound of running gushing water and thought the water pipe had burst. I was pretty horrfied to find a lot of water spilled over the couch and on the floor, took me all day to clean it up and re-home the fish. Letting myself into friends houses.
I'm taking the importers to the disputes tribunal, they have told me I'm the only one to have had this much trouble .
Insurance won't pay out for the syphoning of water over the tank that has stained the carpet.
