This is just terrible!really feel for you,so so sorry this has happened.
Make sure the new tanks have polystyrene under them next time,no glass is completely flat and wood moves over time in a damp environment,ive heard of many tanks that have broken this way over the same time period...its a time bomb waiting to happen if you dont use a thick enough gasket between the glass and the hard surface its sitting on.
Again im really sorry mate,what a start to the year,things can only get better.....look forward to your new fish room and try not to look back too much.
Just Toby;4774781; said:CORRECT! If there are any other tanks like this they need to be drained and put on polystyrene straight away, I have seen tanks sitting on ply crack before.
Can you tell me what kind of plywood was used with these tanks?
Thanks for the advice. I will put all the tanks on a polystyrene.
Its really sour, the professional aquarium builders I spoke to and taught me how to build tanks said that the larger tanks should be glued directly on the plywood(the water resistant ones, the tropical(hardwood) plywood I use is the type that can be submerged for 10 years in water before the glue goes bad and the wood rots). According to them this gives the bottom more stability and better weight distribution, which sounded like sound advise then.
At the moment I have 15 aquariums standing on plywood and one has been laying for it on 5 years now(it was moved from my previous house to this one as well) I am very happy that this one is still in 1 piece as it is a 1300 liter(360 gallon) tank
