Hi, I am under the suspicion that my decision to add Fe DTPA , because of my hard water, may have sth to do with fish deaths.
I believe I might have been overdosing Fe. What I did is calculating for EI on Rotala Butterfly and instead of making two separate solutions one with TNC trace and a second with Fe DTPA 11%, I just made one solution adding both substances.
It took me a while to put 2 and 2 together but since I ceased dosing I haven't seen any symptoms in fish. The main symptoms was some of the fish darting and spinning uncontrollably and dying soon after that.
I am not 100% sure and haven't ruled out a disease but it is very strange to see all the symptoms soon after dosing Fe.
The fish were mainly white cloud minnows.
