I have a question in regards to using water conditioners. I use stress coat By API in the recommended dosages currently. I have been doing water changes on some of my tanks several times a week and though I use a water conditioner for chlorine and chloramin I am wondering if in the brief moments before the chemicals are removed if any harmful effects can take place on my fish. I know the water conditioners work fast but If I am cleaning these tanks as much as three times a week or even everyday could I be doing my fish more harm then good?
