Cool! Glad you figured it out....but yes, you definetly need to break down the cloramine too....the difference with chloramine and chlorine and the reason some water companies are using it (mine started about a year ago), is it doesn't break down on it's own as quickly or easily as chlorine...with chlorine, you can get rid of with with aerating the water very well for a while (not sure how long but I know it's not longer than a day or 2), but with Chloramines, you could have very heavy aeration for weeks and still not get rid of it, it has to be neutrilized with chemicals.
Keep us updated, I'm anxious to hear how your fish do with this new way of treating your water.
