Hi, Just joined. I have been playing with hobby aquaponics for some time. Done some barrel ponics and a larger 2 tank system. Now fancy moving onto something a bit bigger. I'm based in Thailand and economies of scale and labour all call for different considerations to Europe or USA. That said I am very keen to see other peoples spread sheets and see how thy have developed them. Would be great to not reinvent the wheel. So thanks for having me on board and look forward to joining in discussions and finding spread sheet.
