Yes its always best to start your own post. if some people have read this post they may not see your post, but dont worry now.
when I first started keeping aquarium fish I had a few ick cases. this was because I missed a few simple things that are easy to put right.
1) I never heated new water when I done a water change. always try to heat new water or add cold water very slowly.
2) make sure any new items, ie plants,fish are not infected.
3) keep your water in tip top condition ALWAYS.
I would treat your problem the same as above. do a large water change to make sure your water is in good condition. up temp to 28c, add salt,add white spot curer. don't do a water change while you treat unless your water becomes poor. keep check on water conditions at regular intervals If you do need to do a water change during treatment add meds to new water to replace those removed.
