Is there an easy test for oxygen content in pond water?
I have an air pump with twin outlets combined into one, feeding an airstone
in the pond. Is there any advantage in putting a stone in my box filter?

Everyone seems to have answered positively to the airstone being in
the filter box; and this may well be the best use of the two outlets.
But I will at least mention that this will probably not do lots for
adding oxygen to the pond. Remember it is the air bubbles breaking
the surface of the water that actually make the oxygen exchange into
the water. JMO
