I have recently acquired an AIO pump and am enjoying it very much. Clean up is easier than my old auto siphon, because I can draw soapy water followed by fresh water through the siphon tube. But I have a question about drying the inside of the siphon tube. It takes about a week to dry inside, and I'm not sure if being wet that long would encourage anything to grow in there. So my question is what is your last step in cleaning the siphon tube. Would it hurt to draw some air through the siphon tube to dry it?
