oliver id love to see how to test the idea of separating the electrodes ---without zapping a fish --I was thinking in a bubble tower type setting

and yeah I was definitely talking about HOME-MADE SEPERATOR --THEN JUST PUTTING THE OXYGEN OUTPUT RELATIVELY CLOSE (POSSIBLY ATTACHED TOO) TOO MY AIR PUMPS INTAKE --omg I hate caplock grrr --- im guessing that if I pumped PURE oxygen into the air pump itd be more dangerous than just putting it a millimeter away so its all going into pump --but at least some regular air goes in also -- to dilute the oxygen saturation inside the airpump----- another idea ive had is --juts cll the manufacturer and ask if theres any spark chance inside their air pump--and let them know id be running pure oxy into it & see what they say ???
