Changing gravel

[silver]

I know, that's the funny thing!!! I've had this particular filter for 14 months prior to this incident. You would think that SOME bacteria would have still been in the filter......I don't "clean" it when I change media........ There's all these snails in there It was just really wierd that my gravel held that much bacteria???

Did you do a water change at the time of changing gravel perhaps due to there being more mess than you expected?!? Perhaps with water you didn't dechlorinate thus knocking out the bacteria population. That is the only thing I can think of, off hand.

NOPE I never add water before dechlorinating but I did clean off all my plants that same night.........with bleach water But I rinsed, rinsed, rinsed and then rinsed some more in HOT water and also let them sit out and dry for about 20 minutes....... But I used soooo little bleach that I just wouldn't think that would do it But, you never know......perhaps.....

Wait, I also was medicating at the time because of an ongoing fungus problem......hence the "cleaning like mad" that I was doing!!!

do you think the treatment killed off all the bacteria?

The medication wouldn't kill the bacteria (I don't think ), it would be the exessive cleaning that would do it.
