I posted a question about high nitrite levels earlier tonight. I have a 55 gallon tank with 4 chichlids and 2 algae eaters. I took some pictures so you could help me figure out just what kind I have but I can't get them to upload. Any help with this would be appreciated. Also if I do a 10% water change daily to reduce the nitrites do I need to add anything other than the chlorine remover. Should I add any more of the Stress Zyme? I put it in on Monday when I did about a 75% water change. Thanks again for all your help!!
