if your seeing a improvement in your fish you will be fine, however at night (lights off) plants revert from produceing oxygen and switch to co2 if memory serves me right. over the short term you will be fine with the air stone 24/7. but in the long run this will gass off the co2 in the tank and your live plants will come to a crawl if not stop growing all together without co2 and you will see a algae outbreak. its easy to treat the problem but to prevent that is where our challenge comes in.
i would reccomend adding surface movement during the day via a hob filter or even a powerhead close to the surface but not a air stone. maybe putting the airstone on a timer with your lights so that it kicks on when lights go off will help with the overnight co2 buildup and keep the fish from gasping.
