ok, right now 2 of my friends are having a most childish conversation online, so I shall blog!

Finally bit the bullet, and bought a pH controller unit ... =D Sometimes yx is a REALLY bad influence on me. =( And my wallet.

Me: "Hmmm ... dunno if I should buy a pH titration kit, an electronic pH pen reader, or a pH controller?"
Yx:"The pH controller lah ... " Followed by a launch into some very sensible reasons why. And so I relented, and bought it finally.

Pics coming soon!
