Most fish can adjust to pH without problems, however many plants grow much
faster in their optimal pH range. pH testing won't tell you the KH value.
Many plants require a minimal level of KH (this is the CO2 level in your
water) to grow. If you want fast, beautiful growth, it is worth trying to
change. Unless you are injecting CO2, there isn't much point to changing pH,
GH, and you'll have no control over KH. Check out the optiumal growing
conditions from some of the website vendors.

I read alot about KH and Gh on here....I've also seen the chart relating
it all to PH.

I have a Ph test kit, But I'm not sure I'm operating at optimum
conditions...

Can someone tell me What my goals should be(Numerical values) and how to
obtain this info and with what product??



I wouldn't bother trying to adjust pH or KH. It's not worth the hassle.
Plants and fish aren't that delicate (unless you're trying to breed
wild-caught
discus or something).

Your KH tells you what pH you should aim for (via CO2 injection). See
this
article and chart:

If your tank is not CO2-injected, I wouldn't worry about pH, KH, and GH at
all.
