Fish Addict
Your filter should be fine since your tank is not overstocked.
The airstone is not for looks, the motion of the bubbles and popping on the surface actually oxygenates the water. Even the action of fish moving will oxygenate the water, but since they're moving they all take in the oxygen in the water. If you see the fish are always on the top and they look like they're gasping for air, then this is a sign they there is not enough DO (dissolved oxygen) in the water, so adding an airstone stone, powerhead, or a bigger filter will help.
You can crush the flakes in a ziplock bag. It let's you crush to a very fine powder, but it's not necessary with the guppy fry, since they are big enough to take bites out of small flakes.
