Keep in mind that killing lots of weeds in summer and their quick death and decay can cause a large dissolved oxygen loss and this DO sag can kill fish which will be most noticeable in the morning. BE careful and watchful.. Weeds are always best killed in spring when lots of DO is present and weeds are smaller biomass.
