"I brought some test strips from Petsmart from the aquarium section. I tested my pH around mid-day, today (8/19) and the pH looked to be about 6 (barely on the test strip; actually, the last color code on the test strip). Now, at 9:30pm, I used another test strip and urinated on it. IT WAS PALE! IT DIDN'T EVEN REGISTER ON THE STRIP. Now, at 9:49pm, I urinated again but this time I did it in a plastic cup and followed the directions and swirled the stick around. Looks to be between 6 and 6.5 (can't tell which color it's closer to).

Any advice?
What should I do?
How long does it take to go from an acidic state to an alkaline one (registering on a pee stick)?
Has anyone EVER achieved alkalinity to get rid of toxins/disease?"

It looks as if you are very normal.  Neither your urine nor your saliva measure your body's pH level.  You can only find out that level by measuring the pH of the blood and if you read the article below it is very difficult to change that level no matter what you do because your body is a finely tuned machine and is constantly in the process of adjusting your pH level to about 7.35 to 7.45.

Can You Make Your pH More Alkaline?

Your body has a complex system of checks and balances to keep its pH in a normal and healthy range:
7.35 to 7.45. When your pH shifts outside this range and becomes too acidic or too alkaline, your body
automatically corrects itself to bring things back to normal by:

• Increasing or decreasing respiration - When you breathe more rapidly, you blow out more
  carbon dioxide. This raises your pH so it becomes more alkaline and less acidic.
  Conversely, slowing down your breathing causes you to release less carbon dioxide,
  which lowers your pH making it less alkaline.
• "Mopping up" excess hydrogen ions - Neutralizing substances in the blood such as
  bicarbonate and hemoglobin, mop up excess hydrogen ions and prevent pH from
  becoming too acidic.
• Eliminating the excess - Your kidneys excrete excess acidic substances into urine
  to prevent pH from becoming too low. Conversely, if your pH starts to become too
  high or alkaline, the body uses similar tools in reverse to bring down the pH.

The bottom line: The body fights hard to keep your pH balanced. It's nearly impossible to achieve
and maintain a high-alkaline pH for a prolonged period of time.

Are Urine and Saliva pH Test Strips a Good Way to measure the Body's pH?

The only way to directly measure the body's pH is by testing your blood. Testing your urine only tells the
pH of your urine. Urine is naturally more acidic and has a lower pH (~6.0). Similarly, saliva test strips only
measure the pH of your saliva, not the pH of your blood.
