| benifits should not be lost, marks right. if water does get to saturation level at about 8mg oxygen per litre, depending on temperature and salinity and height above sea level haha. (theres charts out there if you want to know.)
it can only get reduced if something uses it up, not by traveling through a clean pipe.
i think the concern is that there could be even more earation going on if it falls thru trickle and hits the stale pond water, turn up the flow rate ever so slightly will beat this concern.
still id go so far to say that when a healthy flow of falling water hits the water in a pond directly below a trickle tower that the water below the trickle that may get disturbed up so as to make contact to the atmosphere is so close to being saturated or atleast of equal oxygen content to the water falling through the bakki that it doesnt make a slight enough difference. hmmmmmmmmm. |
