Hi Jmwoitallq, sounds like the tank is going thru a mini-cycle. The larger water changes will help ease the tank over this hump. Are the fins getting worse? Also if they have been tattered for a while they may need to be trimmed. I have a heckel like that.

Note that one of the hard rays is broken and that can not be fixed. However soft fins can be trimmed like Al shows in this thread http://forum.simplydiscus.com/showth...Heckel+haircut.
