I have a Milawukee SMS 122 PH controller. However, the PH probe that it came with would not work in situations where there's almost no KH. Would upgrading to a lab grade probe work?
Next question. I'm trying to understand the role of PH a little better. If I'm using RO/DI water with no buffering capacity, it would take only tiny amount of PH up or down to increase or decrease PH correct? Now, hypothetically, if I set up two tanks with RO/DI water, one with PH of 8.0 and one with PH of 5.0 - both using tiny bit of PH up or PH down. If I suddenly transfer fish from one tank to another, would they die of PH shocK? I'm inclined to say NO. If the water was very well buffered, then PH shock would kill this fish. I'm just a little confused.
