Yes I did a search and I could not get a good answer to this question. So allmy water chems are at 0 exept my nitates which are now at the middle color on the card..dont remeber teh specific number...How does that happen without any of teh other chems going up? I recently had a bout of
ICH that appeared shortly after adding new fish I dont know if maybe the meds could have had something to do with it

So for now I am starting to do daily water changes and I put the nitrasorb back in the filter that I took out when treating for ich..any other suggestions?
