It seems lots of folks use Alkalinity to mean pH or Hardness (dKH) as interchangeably, as Kim Kardashian interchanges "OMG!" with "Let me take a Selfie".
These are (2) different things:
- pH is the level of acidity vs the level of alkalinity (base) on a pH scale
- Carbonate Alkalinity is the level of dissolved solids (Carbonate/biCarbonate Hardness) on a dKH or mg/l or ppm scale
With that said, after weeks of searching and no answers - I am hoping to find someone who understands the difference between these two things, and can answer a question.
How do I increase pH without increasing dKH? I want to increase the Alkalinity of my water (pH) without increasing the Carbonate Alkalinity (dKH).
I already have a high Carbonate Alkalinity, so I don't need or want to increase dKH. The Calcium is also high - I know there is a correlation to dKH. However, no matter what I do or how many water changes I perform, and yes - I have added both an air pump, and piped the inlet for the skimmer to a fresh air supply - no matter what I do, I can't get the pH to increase past a 7.0.
I purchase all my water from my LFS. They use Red Sea as their salt and the water is reverse osmosis.
Could it be a magnesium deficiency? Crappy salt? I'm really at a loss for what causes a low pH and how to increase it in an isolated manner without increasing dKH too.
Thanks
Cindy
