Treat RO/DI water to raise the PH before making water changes?
3. Of course your suggestions. My fish which range from various tetra’s, angles, guppies and loaches seem to be happy but I am not comfortable with a pH of 5.5. The GH reads about 75-100 < Well water is always a little tricky. Take your pH readings directly out of the tap and then place some water in a 5 gallon bucket and let it sit overnight. The next day read the pH and compare that to the reading right out of the tap. If the pH right out of the tap is lower then there is probably some CO2 (Carbonic acid) in the well water. You should then let you water sit for 24 hour before making any changes to the water chemistry. I would recommend using a buffer to bring the pH up to a more stable 6.5. Check out some products by Kent or SeaChem to buffer the water. Add some to a bucket to get it where you want it and make sure it is stable before slowly adding it to the aquarium. All changes to the aquarium water chemistry should be gradual to avoid stressing the fish.-Chuck> Thanks, Johnny Big
