Would like to thank you all for all the help it has made pool care a lot simplier. Determining when to shock have a taylor k-2006 test kit My reading are CL 1.6- COMBINED CL 0.5- PH 7.4-AL 100-HARDNESS 180-CYA 40 .what would the readings be if I need to shock pool? again thanks Jerry

If you are not having any particular problems, adding enough chlorine 1x per week, to take you up to the Best Guess shock level, certainly provides some safety factor.

Also, if you were using the 0.2 ppm / drop dilution of the DPD-FAS test, then 0.5 CC is a bit high, in which case a shock dose would be appropriate now. BTW, you do NOT have to stop swimming when you shock, except to give the chlorine time to mix.

Is CC what determines if you need to shock ? And what is the normal reading if you don't need to shock? again Thanks Jerry

[PoolDoc]

There's no absolute answer; most of the time, if it's more than the minimum reading, shocking is a good idea. But, some pools tend to run a bit more CC, and if it's not causing a problem . . . then it's not a problem. The minimum reading is 0.2 with the 0.2 ppm drop test, and 0.5 with the 0.5 ppm drop test.
