To decrease the pH (make the water more acid) by small amounts, I have used sodium hydrogen sulfate (also called sodium bisulfate).



To increase the pH (make the water more alkaline) I have used small amounts of sodium hydrogen carbonate (also called sodium bicarbonate).



You can also purchase kits at your local aquarium store that will help adjust the pH.How can u change the pH? plz help?
You should go to your local aquarium store and buy some pH adjusting solutions. You can't just add any acid or base to raise or lower the pH. That may kill your plants. They sell specific solutions for aquatic plants.
