So PH will affect KH/GH right? or vice versa?
I keeping RCS , so PH or KH/GH more important for them?My shrimp die from 16 to 8. These 8 look like stable but they dont molt in 2nd stage to breed, so which 1(PH or GH/KH) i should concern?
Sorry for the noob question. I dont have ph or kh/gh indicator but plan to get them in the future.
hmmm.. i would say PH equally important as GH
if u keeping shrimp.. haha

bcoz
GH is basically measurement of Magnesium (Mg+) and Calcium (Ca+) ions in ur water, which are important for shrimp, snail etc with shell
KH : the term 'hardness' in KH is somewhat confusing because it does not actually measure hardness, but rather the
alkalinity (buffering capacity - ability to neutralize acids) of a solution to resist a pH change. The higher the KH, the more stable and resistant your water is to pH swings. A KH of 2-3dKH is generally accepted as the minimum to maintain a stable pH.
PH, KH, GH.. all of them are related to each other

its kinda complex to explain everything in real sience.. but u can get the basic idea from chart below
for test kit, dun buy API KH/GH test kit.. not accurate, too bad NA dun hav Sera GH test kit
