Is onion vinegar ok to use as a PH shifter ?

Hi all, my tap water is around 8.0 PH and i`m using a few drops of vinegar to lower it to 6.5 PH. Is this acceptable ?


Regards.

Onion vinegar?
No, cannabis plants prefer a nice white wine tarragon vingegar, lol...

I'm just kidding.

Plain cider vinegar works as an emergency solution but if you are dealing with tap water that is consistently high, you're REALLY going to want to pick up some 'real' pH adjustment chemicals.

Thanks stinky i`ll try my local aquarium store.
