JamesW,
I did not state Chlorine will do "anything" to nitrates I simply stated that they can be "controlled" by higher levels of chlorine. Perhaps you misread what I wrote. But I am not sure what is meant, by you, in regards to the all encompassing word "anything".
The only way to remove nitrates completely would be to drain the pool, not a viable option here unless one were to do it every time they sprayed.
There is another option that is more complicated, the administrators of this site have requested of me not to discuss it, as it is both more complicated, and somewhat confusing to "Newbies". I will honor that request, and I think their decision wise. Also it too would be a waste of time as this spraying is ongoing.
If shocking and then maintaining higher levels of chlorine does not work, as stated in my post, the best solution would be a full water analysis by the agricultural extension of the state or municipality, to determine what might be going on.
The ingredients of the spray used are listed in the MSDS, it is "Chlorothalonil", this spray is clearly mentioned in a prior post as the spray chemical "Bravo", if "Googled", it "Bravo" is mentioned in my post and another posters.
Additionally there are a number of scientific papers mostly regarding the increase in nitrates if "Googled", in respect to this spray.
The other spray ingredient that might have been used has not been listed by Michelle W. At the present time no information can be determined.
The fungicide solution "Bravo", does not contain copper if the MSDS is "Googled" .
Reading through all the posts might possibly have made you aware of this chemical's presence and its ingredients. Although I would agree that the various posts are somewhat confusing, unless extra time had been taken to read slowly through the posts over a day, or so. And time taken to "Google" them.
Copper is an algaecide, and I can see your thinking that too much copper may have turned the pool green , but based on numerous "Googled" papers the more likely cause is, as stated in these papers, is increasing nitrates leading to algae.
Maybe you might be correct we will have to see. But more careful research lays the problem at the feet of increased nitrates leading to a slow algae bloom, although slow careful research does not always produce the correct answer.
