Pool Shop Testing, used for personal use?

[CarlD]

Computerized testing of water is expensive, requires calibration and, ultimately, is less accurate than proper drop testing. PoolDoc is fully aware of all the electronic testing tools out there--and completely skeptical of all of them

I spend a minute or two a day testing my water for chlorine and pH, and 15 minutes once a week testing for FC, CC, pH, T/A and CYA. I log it in a spreadsheet.

Thats the way I have it now, only diference is that I took a Visual Basic class at school, and my final project I made a custom pool software that inputs the test results, logs them and the time and date they were loged, spits out custome reports, calculates what needs to be added and by how much by the current gallons of the day, and inventories pool chemicals and tells you when you need to get more. Teach only gave me a damn B+ LoL

My local (not L's) has one of these and they butchered my first water sample. Granted it was mostly the fault of the operator (young kid) but they had my ph below 6.8 and everything else off the charts one way or the other. With the complexities of pool water I don't think a single machine without constant calibration can provide accurate results.
