I got my first tank with a filter today. My betta has ich though and we are treating him with medicine. I wanted to know if the filter will filter out the medicine? Also, with a filter how often do you have to do a full water change??
Carbon filters are good but not when treating fish with medicine because carbon "sponges" up medication. you shouldn't use carbon when medicating.Beta316 said:Yeah the starter filter kit came with the carbon filter. Is a carbon filter bad...should I get a different one??
