To many Airstones = High pH?

Quick question, can to many air stones in your reservoir cause your pH level to rise? I don't understand why my pH rises so quickly after I adjust it?. Any help would be awesome........

No it shouldn't. Do you have any metal in your res?

Air stone will not increase your PH. Whats your ph/tds/water temp and what nutrients are you using?

I have a meter that gives false readings if I stick it where the bubbles are,try takeing a glass off nutes out of your res and test it,if you still have the problem you got something going on in your res

does metal in the res raise ph? i have some stainless steel in mine to keep my airstones from touching the side of the res and vibrating. the sound is annoying

no metal but my temp varies depending if its day or night I dont have climate control yet. My inline fan is way to big for my grow room so my room temp stays just a couple degrees above outside temp when my lamps are on. Drops tremendously as soon as my lamps shut down for my 4 hrs of night. Any suggestions? I'm using Flora Nova nutes and I currently have about a 350ppm at 6.35pH and like I explained earlier my temps varies.....Thanks Guys!!

Air stones can increase pH to a degree - CO2 passing through water does effect pH. Easy way to test it though - turn off your bubbles and agitate the water to let it off gas and see if the pH changes.

This is the case with all my blue lab meters and many other brands
