Oh, I have a 29 gal tank also.
Please do not use the pH adjuster chemicals in aquaria with fish. Rarely do they work, because the tank water pH is where it's at for a reason connected with the carbonate hardness in the water and/or the biological equilibrium in the aquarium. While these adjusters may raise (or lower) the pH temporarily, within 24 hours it will likely be back where it was. Result is pH fluctuation which is significantly more stressful on fish that a pH outside the preferred range.
A partial water change is a safer method--however
, this can be disastrous too depending upon the reason for the pH drop.
What sort of fish (species) in the tank? And do you happen to know the hardness of your tap water?
