I guys , I have a 110 ltr tank , added some new fish and now I can't get my ammonia under control , I have lost 13 fish in a week and a half ! I got an external fitter and used amolock to try settle the problem but not looking good . Any suggestions would be greatfully accepted . I have just carried out a 50% water change ! Thanks in advance
