The OP said he would leave his off during the day when it is hottest, I thought that is when you would want it on?



What is the water volume in your pond, and what is the GPH that the 5 diffusers move total per hour?

Reason for asking is that the diffusers should turn the volume of water over between 1-2 times per 24 hr period. Without knowing that information it is impossible to correctly answer your question.
