Another suggestion from up north...
Often the only species raised in our neck of the woods are trout.
Raising trout in small dugouts or shallow ponds can be tricky.
Aerating on a timer just at night is a solution, but even that fails when night time temperature is warm... we do get heat waves in the summer!
What I found works best, instead of the regular timer is to use the Kasco Marine Temperature Control device like the C-10
http://www.de-icer.com/products_c10.htm It is marketed as a tool that allows your deicer to start when freezing temperatures are reached, in fact you can set it much higher to say 67 F or 22 C and you will never have aeration going on above that temperature.
It allows to aerate only when temperature is bellow a certain threshold, so some nights you wont have aeration, but other days, you could aerate while a cold front passes by.
That way, we can keep aerating disks or bubble tubing at the bottom of the pond and circulate water without adding extra heat to the pond. In fact, we even have measured lowering temperatures of up to 2 Celsius (about 5 F)in 24 hours.
Works for us who raise trouts in shallow ponds and are typically not successful.
Aerating a well sounds ok too! ... my two cents!
