I didn't mean to offend. I guess I'll stick to the fact and not attempt any humor.

What I meant by not needing any of the products is that alternatives that are less expensive and require no maintenance are out there. Swing arm salinity hydrometer, PH test kits. In my experience ( PH monitor, refractometer) they need a great deal of calibration and must be kept clean. Plus when there is a reading that is not normal the first corrective action is to clean and calibrate the unit. PH meter (Pinpoint) with the AC adapter are really susceptible to electronic noise and can give erroneous errors when calibrated perfectly.
