Newbie question about aeration

I have a newbie question about aeration. I purchased two six-inch
airstones, some silicon tubing, a T-connector, and an air pump from my
local PetSmart. I ran the hose from the air pump into the tank and
into the base of the T-connector. Off of each arm of the T-connector
is about six inches of silicon hose, at the end of each of which is an
airstone. When I power the airpump, only one airstone comes alive
(and boy does it!), the other just barely even fizzles at all.
Changing the airstones to the opposite arms of the T-connector, I find
that the same airstone bubbles, and the same one doesn't. I figure
maybe my air pump isn't powerful enough to push two six-inch stones,
so I return the pump for a larger one (more power! *grunt grunt*).
Much to my surprise, the same thing happens, just the bubbles coming
from the one that activates are more forceful than before; the other
airstone still sits silently. I can only conclude that the airstone
that doesn't "work" has more "resistance" than the one that does, and
the air escapes through the path of least resistance. Is this the
situation an adjustable gang valve is designed for? Should I use a
gang valve and "dial back" the pressure to the "least resistant" one
until I get fairly equal activity from them both? I assumed a simple
T-connector would be fine, but something obviously doesn't work the
way I assumed. I apologize if these questions seem naive. What is
the proper way to do what I'm trying to do?

Thanks for any insight or advice provided!

You got it.. Use adjustable valves. Or separate pumps. Some air stines are a
pain for this.

I have an air sone about the same size that starts good and very quickly
stops working, possible bacteria keeps clogging it up. I rubbed my stone
back with sandpaper to make it thinner untill it worked roughly the way I
wanted.

Now I have given up on air stones, I just use power heads with the air hose
added, it airates the water better and gives better circulation.
