I am TTC boy this year (around June, 2011). I just got my digital ph checker along with storage and calibration solutions. In regards to calibrating the digital ph checker, can I store the ph 7 and ph 4 buffer solution after using them for calibration? I believe that, I am supposed to be taking a small amount of ph 7 and ph4 buffer solutions in a container for calibrating the ph checker..
The second question I have is, do I need to purchase cleaning solution?
Also, for checking the cm ph, do I have to put the cm on the bulb of the electrode to check the ph?
Note: I read all the FAQs and the swaying guide, but the above things are not very clear to me. Please help me ladies!!!
