not usually, you can do a little science project to figure it out! Take two cups, full them with Tap water, Test one immediately, treat the other with you conditioner and leave it out for 24hrs and than test. Ph.. Tap will "gas off" over the day to reveal your true ph.My fish seem fine and the PH is steady so i probably wait before purchasing it. Do water changes affect PH levels?
Your pH is totally fine, there is no reason to add chemicals to mess with a steady and acceptable pH.
It is important to share advice in this community; however, it's also important to try to answer the actual questions that our fellow fish keepers ask.
These forums are read by many aquarists who may have wanted to know how to lower pH and not necessarily if their pH is "good" or not.
