Oh also is it true your Filtration Penguin 400 bio wheel and a large air stone can cause higher ph
2 Turquoise rainbows 5 Neon tetras ,2Molly's 3 guppies
4 albino Cory's.

We're getting things a bit mixed up here. Can you clarify, do you have a house water softener system? Or is the tap water straight from the water mains?
First, on the GH and KH. Find this out from the water people's website [post the link if you can't figure it out]. There is no need to waste oney for a test kit for GH/KH unless you are going to be adjusting it, and that may not be necessary. Post the numbers, or the link.
Second on pH, this is related to GH/KH, and will be whatever it is out of the tap. Both GH/KH and pH depend upon the source of the tap water. The pH can lower in an aquarium, or rise if calcareous substances are present, but it is tied to the GH/KH and attempts to adjust pH without dealing with the other will almost always fail.
There is a relation between pH and the filter/air stone but it is not that significant and I don't want to go into all that here. BTW, the pH numbers, are these your own tests? With which test kit? And when testing tap water, always put some in a jar with a lid and shake it very vigorously for a few minutes; this outgasses the CO2 which if not done can give a false reading.
The fish mentioned will be fine in moderately hard water with a basic (above 7) pH, except for the neon tetra. The rainbowfish is a sholaing fish that should have a group, say 5-6. This species is not yet in our profiles, but I can say more later.
