Hey, are you online? 🙂
Technical Advisor:
Yes, I am.
Client:
Ah great. I wonder, do you sell buffer for aquascenic? PH, Redox and salinity.
Technical Advisor:
Yes, do you know the value you need? Just for pH and redox.
Client:
Well thing is, I have had problems with my system all last year and this year. But now I suspect it's either buffer or it is probes. So some of them I need.
Technical Advisor:
Right, first test your probes.
Technical Advisor:
Not like this, I need to check the documentation.
Client:
Okok..
