Morning all you smart guys/girls

Got a question that is bugging me.

We have 3 ponds here at work, they are huge and are prob called Damns if you will :p Now 2 of them have fountains and the other one has no fountain so the water is still.

Now, the one which is still the water goes stale, but the other 2 not. Now I know moving water doesn't go stale. My question is why? I mean they are all exposed to the same conditions and what not, but the water doesn't go stale in the 2 ponds/dams where the water is moving. Is there an explanation for this?
 
Churning the water allows all the water to come in contact with oxygen/light?
 
How do you know the water is stale, did you taste it? :sick:

Churned water has a higher percentage of dissolved oxygen, because of what carudden said.

hehe, no I never tasted it. But it's pretty clear that pond/dam water is very stale :sick:
 
There is always movement most probably meaning there is less chance of algea etc to grow in abundance...

Some of the bacteria only grow(the worst) in de-oxygenated water...
 
hmmm... well it's simple.
When you churn up the water, the algae (which is responsible for the discolouration of the water) is unable to glow and gets destroyed in the process... It's the same as when you look at a calm, slow moving river and a rough river, the water in the calm river will have more algae as the algae can recessive more constant sun light which it needs to man food. So what's happening is that by making the water turbulent you in effect turning the algae from the sunlight rich top layer to the sunlight deprived bottom layer of the "pond". this means you disturbing the alga's food production process and without food it dies.
The other thing that fountains and rough water does is it compresses the alga's contractile vacuoles when there's a rapid pressure change which, in effect makes those green little bastards explode from the inside(because too much water is getting passed into the cells via osmosis and as a result the cell will expand and 'pop').

As for bacteria, they are a little more hardy then algae, and they will still be present in the water, but the rapid compression caused from the fountain should help kill off a few of the bastards.

Also the reason why the water looks more pleasant is because there's a constant amount of oxygen being dissolved into the water which makes it clearer :).

I hope I answered your question fully :)
 
AHA !

Thanx guys :) Now I understand it.

O and Scotty, for a petrol drinking kid, you are actually pretty smart :p

Much appreciated you all :)
