Cotton swabs safe for aquarium?
I've been looking for something to optimize the gas exchange with my air pump/CO2 injection. I've found that sticking the end of a cotton swab into the end of the air pump is very effective at minimizing bubble size and maximizing surface area, but I'm not sure; is a cotton swab safe to put into the water?moar tanks plz
