I will soon be upgrading to a 75 gallon tank, and when I tested my aquarium water the other day I realized that I have a slight problem. My KH was about 1. As soon as I put my first drop of liquid in the tube it turned yellow right away. My pH was about 6.6.
Now, I plan on possible having this tank heavily planted and running CO2 into it but I realize that I am limited because my pH will crash and be too low for the community tank that I want to keep.
Yesterday I added just a teaspoon of baking soda to my current 29 g to see how much the kH would go up. I was pleasantly surprised to see that it went up to 4. However, the pH went from 6.6- 8.0!!! This concerns me.
What did i do wrong? Will crushed coral have the same effect? I want to know that my tapwater can be buffered so that I can safely inject CO2.
It doesnt seem right that the pH would rise THAT much from buffering my water.
