where can i get something to test the ph level of my water?

hi i am a new to growing. the title pretty much explain it. I am looking for something cheap to test the ph level of the water i am using to water my plants which are in soil.

Go to a pet store or pool supply store. They have ph test kits for under $5. Walmart or Home Depot should have them as well.

I'dadvise you get a roll of ph test paper .. test your water runoff ... use pH down to adjust your water .. Iron Sulfate adde to the soil .. will help lower pH but shouldn't be added to soil around growing plants .. it can burn them ..
