Pond Boss Forums AERATION Should I aerate? All or Nothing

If you measure at the upwelling bubble column, you can tell if you are moving "dead" water and have a common sense approach to how efficient your system is...or how efficiently you are using it. For example, if we run a system for 8 hours daily, shut it off for 16 hours, turn it on and measure zero oxygen, the pond is either re-stratifying during the off period or the system isn't adequate. If we run a system for 8 hours, shut it off of 16 hours and then turn it on and we have 4-5 ppm O2, we're pretty efficient with it.
