more solids = less DO per volume - physics, if you take a cubic foot of water, add in X amount of ____ material, you need to displace x amount of ____ material. As the amount of carried solids increases the amount of carried do has to decrease - that's my train of thought any how?
No offense but this is not a closed system where if you add X you displace Y. There is still the same amount of water in the pond.
