Can left over bleach in Filter Sock cause Ammonia?

[LeanneP]

I just put a new filter sock that I had soaked in bleach and rinsed by hand several times. I couldn't smell bleach any more. This is the first time I used bleach and within a couple of hours of replacing the sock my corals and anenome closed up and are not looking happy. I just tested for ammonia and I now have 0.1. I have added carbon and an ammonia pad and am going to a water change as soon as possible. I did forget to turn my sump back on for a few hours a few days ago and the tank dropped a few degrees. Is it just a coincidence about the filter sock and I am having a mini cycle from the sump not running or can left over bleach cause ammonia in the tank?

It could I guess. How long was the sump off? You could have a little die off from the return line being dry if it was overnight or so.

Why did you bleach your filter sock? Weekly I toss mine in the washer and run them thru two cycles.. No soap no bleach. I don't have the need to have them come out pure white.

Sump was only off for about four hours. I used bleach cause that was what people were saying on here. This has kind of freaked me out though. I don't think I am going to use bleach any more.

I bleach mine but there rinsed 2x. And dried before use. Never had a issue

I just don't see a reason to bleach them..the hot fresh water will kill off anything left in them.. All the bleach does it make them sparkly white.. I can deal with off white filter socks
