Yer you are right with all that info Alan, I am lucky. But why did so many people, Even Warren with all the calculations, say that yes it would be sweet without it, but it wasnt, Obviously it comes down to the chase, and people saying that it will be sweet is just a guide, but you will not know until you try it....
I cant empty the tnak Alanmin because it is full of plants and fish and it is all perfect ATM. I have glued the middle brace back in (it has been sweet with this brace for a while) But still have 'F' clamps accross the tank until the silicone fuly cures. The tank is sitting half empty now until it cures aswel. I will put some other pieces underneath the edges like you said Alan, once it has dried.
Thanks guys
