FWIW, this pond doesn't get hot - it is continually fed by a stream (or a well when it's too dry to use the stream) - and it is in Vermont
. I understand that brook trout are quite heat-sensitive, but they seem happy in there. They seem to stick to the bottom where it is cool - so I want to make sure they are getting the oxygen they need. Weeds are not currently a problem - pond is clear.
--Now I am wondering if it might make as much sense to run the aerator on a timer at night, hooked up to 110v (it's a short run, just don't love new persistent power usage if I can avoid). If it was just at night, wouldn't use so much power.
