I'll do that.
I called the water company and they told me that my tap water was 8.9ph
and a hardness of 14.3ppm
I tested the water straight out of the tap and the pH was 8.8 and the hardness was 34.6ppm
I haven't, however, let the water sit for 12 hours then tested it. I will do that.
I believe that GH is general hardness and is the measure of primarily calcium (Ca++) and magnesium (Mg++) ions in the water.
Am I wrong?
KH is the measure of bicarbonate (HCO3-) and carbonate (CO3--) ions in the water.
This is what I've been lead to believe.
I'm not an expert about these things and would like to know if I'm on the right path.
I converted the GH to KH using chuck's web page and that's how I got to 2 for my water hardness.
If the water out of my tap was 14.3 ppm, then my hardness would be 0.8.
If you don't believe me then you can give the boston water and sewer commision a call and ask them.
Of course, I imagine that when the water actually gets to my pipes it is not the same as the reading that they told me they took in september, however, I don't expect it to be that different. When I first got into finding out what was in my water, I called them first, then tested it myself and compared. That's how I've come to my numbers. If waiting 12 hours will make a difference for the test, then I'll give it a shot. I hope it makes a difference.
Let me know what I should do next here. How do I lower my pH with my CO2. I don't know how to do that. I know that CO2 will lower your pH,
but I have that cheap system from big Als. My aquarium lid is not airtight sealed, but it has a glass lid. The bubbles are flowing fast.
What do you think?
