If you don't recommend using bubble stones, what do you suggest?
And why don't you suggest it?
I didn't even know they had a new Hobbyist area.

I am so sorry, there are many here who mean well but are just repeating what others have said and don't always do the research. I call them Parrots... lol
Then there are those that ask dumb questions to incite an argument, I cant post what I call them...

Here is a poll, if you would like please add your thoughts.

wow, there are no answers set in stone in this hobby. for your size tank, a filter (what kind are you using) and a couple of powerheads (you call them water pumps) should be enough. Air stones arent used in saltwater, unless you are keeping seahorses and then only an open air line with ridgid tubing.
Please remember this is a friendly community and we have members of all ages. I think the youngest is about 13. young people dont alway word things in a way older people would.
Welcome to the community.

So, I want to have 2 clown fish & about 3 other little fish in my 30 gallon tank.. If I have a filter going,
a water pump (for water current) & 2 bubblers stones, will that be enough oxygen for that many fish
or will I want to increase the bubbles to make sure all the fish get plenty of oxygen?
The last thing I want is to have several fish in the tank and not have enough oxygen for them to survive.
How does one figure out if they have enough oxygen?
You would need an oxygen meter. Never used one and I don't plan on ever getting one. For a 30 gallon with no top and standard shape with the 5 fish you have chosen, oxygen will be fine as others have posted.
With a salt tank the waste numbers tend to become a big issue and the fix will most the time add to gas exchange keeping oxygen where it should be. Keep algae under control so when there is a power outage there still will be no probs.
Powerheads are a clean way of keeping gas exchange good. Koralia and VorTech are good ones.

Aistones are almost always a bad thing in salt water aquariums and as a general rule, they're frowned upon.
As long as you have an open top (not having glass right on top of the water), a powerhead or two (depending on size of tank) aiming at the top to break up the surface of the water, you should be fine. Basically, the top surface of the water should look like a pot of boiling water, if it does, you have enough exchange and don't have to worry about oxygen.

My 2 cents even though some of this was already addressed...if you have a protein skimmer and have some movement on the surface of the water, you will be fine. One of the problems some of us have is the micro bubbles that are produced by our skimmers. I keep 2 airstones in my tank (I keep octopuses that use much more oxygen than the average reef tank with fish) that only come on when there is a power outage, otherwise they are completely unnecessary and can be hazardous. There is a meter you can use to measure dissolved oxygen but I have never seen this as a concern.
One of the disadvantages with the forums is that the emotion is missing. One cannot distinguish seriousness from sarcasm or humor. We all need to relax and enjoy this wonderful hobby
