How to Lower the PH in Your Aquarium
Methods to Reduce PH in an Aquarium Use Reverse Osmosis (RO) or Deionized (DI) Water : RO or DI water is almost pure H2O without minerals. Mixing RO or DI water with tap water can lower the pH, dilute the mineral content, and increase pH levels. Driftwood : Adding natural driftwood to your aquarium can gradually lower the pH.
