After two months of 0 ammonia and 0 nitrites, I suddenly have been getting ammonia showing back up. It was .25 yesterday and .5 today. I did a 75% water change this afternoon to get some clean water back in the tank. About a month ago I saw that my PH was dropping also. It was consistently 6.8 and over time has dropped down to 6 and possibly lower. Can't really tell since that's as low as my API test reads. Any idea what might be going on here?
