Tap water and airstones

Hello, have a question for some of you. I recently started watering my plants with tap water. I let them sit out for 24 hours to get rid of chlorine. However recently I have been filling up a 5 gallon bucket and throwing 2 airstones in and cranking the pump for about 2 hours and then I water my plants. In theory I heard that chlorine evaporates in air, so my question is if I use airstones shouldn't that speed up the chlorine evaporation? I have nothing to measure chlorine so I was hoping someone out there could answer this for me. I have noticed that my PPM drops, but I don't know if chlorine shows on a PPM meter.

Thanks

Why not just get a meter ya cheapskate

chlorine tester, Pools Spas, Patio Grilling items on eBay.com

I have a PPM and a pH meter for now. I'm cheap cause I just had some big bills to pay...lol. I had to get some supplies....wink wink for the garden. I do have the water testing strips and I got a water report when I bought my house, it had low chlorine numbers to begin with. I just want to know the answer, my plants seem fine but I was curious.

Smarty pants.......plus I like bubbles

Oh on second thought they are cheap....

I will do a test with my pool strips and if that isn't helping me...I hate reading strips....I will buy.
