Things You'll Need
- pH testing strips
- KH testing strips
- crushed coral
Instructions
Test the pH. Use the pH testing strips according to the manufacturer's directions. Test every few days and record the data to give you a good idea of your water's buffering capacity. If you are doing water changes or adding water, test and record the tap water or distilled water before you add it to your aquarium.
Test the KH. KH testing strips allow you to test your aquarium water's buffering capacity. This may not be necessary if your pH is relatively stable.
Remove dead plant matter. If you grow plants in your aquarium or use driftwood, be aware that decaying plant material tends to lower pH in your water and decrease its ability to buffer. If you have a low pH or low ability to buffer, look for this.
Add crushed coral. Crushed coral increases pH and increases buffering. Baking soda also raises pH, but even a small amount can cause a big swing, which doesn't change buffering. Be aware that adjustments to your aquarium's pH should be done gradually. A rise of .3 on the pH scale in one day can kill your fish. Add small amounts and test the effects. With crushed coral, you may need a 1-inch layer on the bottom of the tank.
