Hi MF, I'm hoping someone could give me advice in my 29 gallon, I recently added a sump to my 29 gallon eclipse & was surprised to find my ammonia levels being high, i did a quick inventory & discovered my BTA was missing??? I'm thinking when I was aquascaping I might have crushed him, not sure though. So my question is if the BTA is polluting the water and I can't find it, do I continue to do daily 5% water changes until or????. Prior to this weekend I had no traces of ammonia
