Before I swapped substrate to AS Amazonia (1) I had around 5.4-5.5 PH with CO2.
Now I have 4.3, and it strikes me as very low. My KH also went from 2 to 0. I know it's pretty common for this to happen. Is it necessary to raise KH? It's only been one day now with that PH value, and my fish don't seem to mind, so far. It doesn't really worry me, but I figure I want to be on the safe side and consult the more experienced people!
Note: PH without CO2 is 5.38 now, used to be 6.5 with regular sand substrate.
(I did calibrate my CO2 probe recently, droptest show about the same)
