Purchased the TF-100 test kit last year.... Opened my pool last Sunday (6-2-13).
Shocked the pool and ran filter for 24 hours. My wife brought a water sample to Leslie yesterday....
Here are the results.... (new guy at the testing station without a clue)
When I got home about 6 hours later I tested the calcium hardness myself and got 300....
The kit instructions say "add R-0012, one drop at a time, til color changes to blue"
I did this and at drop 30 it changed to a purpley blue..... Is that when to stop or do I need to keep adding R-0012 until it turns to a blue..... I always thought it was a signifigant color change....
Also at Leslie they stoped the test and told my wife it above 500
any help would be greatly appreciated....... Thanks again
