Hello all. So I moved house recently and wanted to take my stingrays with me. Luckily the house I moved into had a good sized shed in the garden which the other half kindly said I could have as my fish house. The shed was roughly a 10fft square. So the first task was getting it ready. Floor needed replacing as it was very weak and whole shed needed insulating. Once that was completed next plan was to biild a ppnd for my rays. Decided eventually to make the back half of the shed a pond giving me internal dimensions of 9ftx4.5ftx3ft. I will.update you as the build gets completed. Firstly here is the floor being built. I used 2x2 for this roughly every 8-10" then packed the gaps with 2" polystyrene and finally laid 3/4" ply over the top so it should be pretty solid.
