I have been aerating my wort using an aquarium pump without an air stone the last few batches. My airstone clogged after the first use and boiling, starsan, pbw dont help. I aereate the wort for 30 minutes before pitching the yeast and cant see a problem so far. I have oxygen in the shop for my torch and may use that in the future but am curios if the air stone is really critical.

As I understand it, the stone decreases the size of the gas bubbles and diffuses the gas into the liquid. Without it, the air/oxygen bubbles will be larger and the liquid may not get the oxygen diffusion levels you're looking for. It may work without the stone, but I think it will work better with one.

i just shake my carboy before pitching the yeast.

No stone or other fancy tools needed.

I know a lot of folks here subscribe to the air stone aeration, but I haven't seen any actual proof that it gains you anything. I haven't seen any major difference between aeration and not, so I just take what aeration I get from transfering wort and leave it at that. I'm very happy with the end results.
BTW, those can not be drunk in multiple count if the day’s plan includes finish carpentry work or power tools.

I have never used an air stone or injected oxygen. I just shake the carboy around a bit. Been brewing for 9 years.

An air stone isn't critical, you can just run the pump longer (about an hour). On there other hand, using oxygen without a stone is a major waste.

After aeration, I put my stone in hot water and let it run for another 5 minutes. Try boiling your stone to clear the pores, it worked for me.
