Hi all, my parents have given me a nano tank which they had for about 6 months , but decided they did not want to do saltwater. I have done some tests and the ammonia is at 0.25 . I noticed the salt levels were very high and have got them down to 0.127(slightly high I know) there is a shrimp in the tank that seems to be ok! My water change today was about 75% and still shows ammonia. Does anyone have any thought on this. I will post a picture to see if you think I have enough live rock. Many thanks.
