+ If you've got a Leslie's guy who said your numbers are fine, and didn't try to sell you something . . . GO BACK TO THAT GUY!
+ If that guy continues to be available to you, you can probably get by with him, but if you want to be sure, go ahead and get the K2006 and learn to use it!
+ Put the ePool in your attic or garage sale. ORP does NOT equal chlorine level, so there's no way to maintain calibration. Ph electrodes drift over time -- in labs, they are re-calibrated weekly or even daily. If you can force yourself to ignore the pH and chlorine readings, it would be OK to keep it. But most likely you won't, and if you don't, it WILL get you in pool trouble.
