Remove some of the minerals from your water by using a reverse osmosis unit for two weeks. This allows your water to go through the biological nitrogen cycle, and naturally filter harmful elements by replacing them with beneficial bacteria. Treating the water with only a commercial pH conditioner to decrease pH levels isn’t effective, since the high mineral levels buffer the water conditioner’s acids.
Water quality is the most important element in keeping a successful aquarium, as well as the most challenging. It must be maintained in a freshwater fish tank to ensure the health of your fish. Water's pH levels relate to its acidity, which is measured on a scale from 0 to 14. Freshwater pH levels of 0 to 6.9 are acidic, 7.1 to 14.0 are alkaline and 7.0 is neutral. Water with high pH levels has high mineral contents. Low and high pH levels create stress in fish, harm their color and growth and may be fatal. Most freshwater tropical fish thrive in pH levels of 6.5 to 7.5.

- Phosphate-free pH decreasing water stabilizer
- PH testing kit
- Peat moss
- Water conditioner
Test your tank’s water with a pH testing kit after two to seven days.
Add a phosphate-free pH decreasing water stabilizer according to the bottle’s instructions. Phosphate-based water conditioners encourage algae growth, which results in increased pH levels.
Arrange some peat moss inside your tank, as it acts as a natural water filter and provides a stabilizing agent for maintaining neutral pH levels.
Change the water approximately once a week to ensure the pH levels stay consistent. Fluctuating pH levels can be fatal to fish and cause disease, shock and death.
Pour the water conditioner into your tank according to the instructions.
Test your tank’s water approximately once a week to maintain a consistent pH level between 6.5 and 7.5.
Write down your water testing results in a log so that you can monitor and track patterns. That will allow you to manage pH levels by making adjustments when fluctuations occur, instead of waiting until they reach unhealthy levels.
