Peach is right down here it gets hot hot. Remember warm/hot water holds half as much D.O. then cool / cold water. I run mine at night only and some folks run 24/7 but I don't know anyone who runs there air system just during the day... but night time is a must as that's when all your plants and weeds are taking D.O. away from your pond not giving it. During the day the plants and weeds give you D.O. If it were me I would wait and save up till I could get a system with a battery. IMO it would be worth the wait.

Lets see what others have to say....

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
