I'll second the concern about oxygenation and lids over the tank - unless you use underwater bubblers. (Rather to my surprise, I've found that I don't need them for a 1000 gallon tank, with a vigorous shower/fountain on the water return. so far my fish are small, though, so I'm watching it.)

Well then, if doing a heat exchanger like that, no problem. If it is a good clean blue barrel then I expect there would be not need to sleeve it either. If the water in the barrel has no salt in it, and the pH isn't low, then the corrosion of the heater will be minimal and it will last longer too. Only thing to watch for would be mineral build up which should be minimal for this usage (unlike what can happen in a home water heater.)<br />

Hello Ron,<br></br>
I too have been looking into something very similar (had a micro one for boiling water for coffee). Great idea...as always, necessity is the mother of invention :-)<br />
Thank you for this link. It will certainly save me searching further.<br />
God bless<br></br>

that would be nice. In the culinary world we use a heat resistant silicone product for casting molds used in sugar work as well as baking. I know for sure its food safe for this reason and am in the process of pricing it out to use in bulk. Maybe just coat a wood frame or even just cast a grow bed. The benefits would be the heat resistance, flexability, and food safe. But i know its going to be more expensive than a spray bed liner.
