I understand you used soda ash for alk but you should be useing calcium chloride to archive a ph upto 8.4ish if you have hight ph use sodium bicarbonate to bring it down.. I don't really think adding pure oxygen is a must. A good skimmer will reoxygenate the water column well enough. If you use vinyl tube and draw fresher air then what's around your skimmer it will help allot. Good luck.
Sorry bin but you got something's mixed up that need a little correcting. First calcium chloride is used to keep the calcium level up not the ph. Then sodium bicarbonate will raise your ph not lower it.
