for what it's worth, keeping a conservatory cool in the heat of the summer (in the daytime) is nigh on impossible in my experience...
However, water is pretty slow in reacting to surrounding air temperature.... for example if you wanted to make a cuppa. and you kettle had bust.... turning the thermostat to 40deg would hardly affect the cup of cold water. So a huge tank of water shouldn't shift more than a few degrees, plus in our climate, we can get cooler nights, even in mid summer so i shouldn't think you'd get boiled fish in the course of 24 hours..
