My understanding is that to get from Ammonia (NH4) to NitrItes (NO2-) and then to NitrAtes (NO3-) obviously oxygen is required, plus the bacteria of course.

The HOB filter that I have on my tank doesn't seem to stir up the water enough to create aeration of the water. The fall doesn't seem to be big enough to aerate the water. In my case, I don't think an air stone could be a bad thing.

We shall see if it causes any bacteria activation because I haven't seen any for 2 & a half weeks.

There will be sufficient oxygen in the water for bacteria. And one must remember that it takes time for bacteria to establish regardless of other issues, although it does occur quicker at optimum temperatures and pH which is probably more significant. More oxygen can't hurt though--unless you have live plants.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

There are no plants in the tank, my LFS recommended not going with plants until the tank has cycled and fish have been added.

Since adding the air stone, I'm only running for a few hours a day at the moment.

Where do these people get their ideas. Live plants is the best thing you can do in a new tank. If you have enough of them, and they are relatively fast growing, you can add a few fish on day 1 and there will be no discernable cycle to you or the fish. Plants need nitrogen, and they get it as ammonium (ammonia produced by fish and bacteria is taken up and changed to ammonium and then assimilated). And plants take up a lot of ammonia, both as nutrient but also as a toxic substance, just as they can take up a number of toxins.

I have set up dozens of tanks in my 20 years, always planted from the start, and fish go in with no issues.

I think this is why new aquarists get confused.

Two different forums, and fish shops have given me completely different solutions with apparently the same end result.

One piece of advice I was given was that if a fish shop gave you advice that resulted in a sale for them, they are more interested in your money than your fish/tank.
