Pond Boss Forums AERATION Systems questions Too much aeration

You'll need to measure it top to bottom. Look at the Fish Kill thread by Charlie B. He found a place that rented DO meters. They are pretty expensive for a casual pond owner to buy. This is something that you need accurate repeatable readings. I'd look into renting one, getting the readings with the different run times, making a chart, then returning it. A good meter will cost.......

I don't know how it'd work if you can't physically go into one of their stores, as I've never used them, but this seems to be a viable alternative to buying one. This is the first place that I've seen that rents them!
