So I've posted already to ask about my betta on the regular forums, but I have a question about some advice I got.I was told to add seachem kanaplex to my tank and remove the carbon in my filters, but I only have one carbon filtration system. Do I need to get an airstone while medicating? Or do I use something else? My betta's popeye is pretty bad, plus I'm worried about his stomach, as it has a bulge in it. Please help!
