pH problems

[PenPen1983]

Well i'm having problems with my pH. It's testing in the yellow (wich is obviously not good) and the pet store keeps telling me to just change most of the water and it should fix it. So i went and changed a little more than half the water and guess what, it's still testing in the yellow. So i went back to the pet store and you guessed it, i was told to change the water again but this time to take my fish out and vacuum my gravel. Now i have doubts about changing part of the water again, so what should i do?

check the ph of the water you are adding. then see what that tests.

if you are not very careful it will mess up your cycle when my ph crashed it made me have to start all over again baking soda will bring it up some without harming your fish either

How old is the tank?

What fish do you have? If you can provide nitrate nitrite and ammonia that will help also.

Test your water hardness. Water which is very soft will not hold steady pH.

Yes, baking soda is one option, as are shells and certain rocks. Forget the Up/Down drops, neve tried 'em, but never heard anything good about 'em. I use crushed coral in the filter.

But first things first...get your results and take it from there. Get both GH & KH of tank and tap.
