Cool, thanks for the help. I know what you mean about hanna meters. I've had more trouble with this meter than its worth. Fortunately I didn't pay for it, its my buddies. He loaned it to me about 8 months ago and within a couple months it wouldn't read anything but EC. So my buddy took it back and ordered a new probe. Then it worked intermitenly for a while before I gave up on it and went back to using the liquid ph tester. Now for some reason its working fine, so I re-calibrated it and its been okay the last few weeks.
