  1. Just wondering what innovative ways people might use to cool ponds if too hot. Sprays? bubblers? fans? paddle wheels? I'm in Melbourne but I'm establishing some 1000-3000 litre above ground "ponds" in a glasshouse. (stock troughs, aquaculture ponds). I can insulate the sides heavily (e.g. rockwool or fill around them with sand to make them "below ground" to minimise temperature fluctuations which in a glasshouse are huge. On a run of 40C days I had some 200l black tubs exceed 45C water temperature (no livestock). Air temp in the glasshouse (with doors open) can hit 70C at the worst for a couple of hours - but this isn't sustained and most nights are ~20-30 but the water holds onto the heat. The larger the body of water.. the lower the temperature increase each day, but I think I'll need sprays, or fountains or something to cool the ponds down at night a bit so then next hot day isn't compounding the heat problem. In Melbourne this happens maybe for 1-2 weeks in summer only. ..so apart from refrigerated chillers and bags of ice - what works best to cool things down?
