PH and AMMONIA Alerts


I have been using the PH Alert and the AMMONIA Alert in my 175 Gallon tank and let me tell you that they are both wonderful. Easy to use, easy to read and best of all they work. I have never had a problem with either of these two "Killers" and my tank is health and my fish are happy thanks to 'ALERT".
