what impact does rain have on pool water. Our pool is still open and we've recieved just over an inch of ran in 2 days. The water level was a little low before the rain (intentionally b/c rain was coming). Does 1 " rain equal 1" increase in pool water level? What happens to the pH.

Yes.....unless your decking is sloped incorrectly and runoff water is allowed to enter the pool.
If you receive an inch of rain in a pool with an average depth of 4 feet, the chemistry will be diluted/changed by 1/48th......i.e. normal rain amounts have little to no effect.
Again, if runoff enters your pool, you have a problem that will seriously affect your pool chemistry and, likely, the quality of your water.
However, people have reported that the agitation of the pool surface from rainfall has a similar effect as aeration, and made their pH rise. I haven't observed this, but I have a solar cover so the rain doesn't really agitate the pool water. My rainwater is definitely acidic but I haven't noticed any particular pH drop, either.

Our pH dropped considerably while we had our solar cover on. Having read that the raindrops would raise the pH level, I took the cover off just before a big rain and sure enough, the pH fixed itself!
Dont make any drastic changes to your pool after a rain for a few days. the pool will take a few days for the aeration (co2) to gas off and it will settle back out. It might change some, but just wait a few days.
