platy problems

Problemes never seem to end. Adult platy with the bent spine just vanished, ick on all 3 platy babies. I was reading the ich article, mentions that salt is OK with the carbon filter. What about the ammonia filter? Can I keep it in as well?
Ok, have you done any of the water changes recommended? every week, it should be about 30 percent.
I personally do not like treating ick with salt, but you can keep your filtration running. It does not absorb the ick but what many people do not know is that they will turn off the filtration and then run it after treatment and they get another outbreak. Alot of times the organisms can thrive in the filter media and bio wheels. So I would take that all out after treatment. But it is recommended when treating for ick to do regular water changes every few days.
 
I did the 30% water changes, one week ago and today, before starting the salt treatment. If I do more water changes during the treatment, I guess I should add salt to keep the level constant, right? What do you treat the ich with, by the way?

Another thing, I recently added a large shell into my tank as ornament. I boiled it before. Today when I cleaned it I realized that by its spiral shape, it holds water inside that doesn't have the chance to circulate. The water inside smell really bad, like something was roting there. After I bleached it, it didn't smell anymore, so I don't think there's something inside, just the bad smell from the water. Might that be a source of bacteria?
