Currently using Salty Shrimp + to raise GH and Baking Soda KH to raise KH.
In my test, I found that...
Baking Soda raised PH.
Salty Shrimp raised PH.
Here's how I conducted the test.
1. Used RO water with PH 6.
2. Dropped a pinch of baking soda into the test tube, tested for PH. Skyrocketed to PH7+
The result was the same for salty shrimp.
What is the alternative to raising GH and KH without affecting PH?
