Need some Help

[hink]

Can not be certain as I never could find the bodies (at least a day) pieces of them maybe maybe, I wouldn't call zero to less than .1 much of a spike and having checked the ammonium weekly pretty sure I would have noticed it creeping up also would have noticed fin burning and labored breathing there has to be something going on when I do weekly testing and 20% water changes to create that kind of spike and that would be from a loss in the tank but I do thank you for your input Northern Reefer
