Ok,
I'm going to shock today with 8 gallons of the Walmart Ultra bleach.Do I pour it around the pool or into the skimmers? I have a vinyl liner and don't want to bleach it .How will I know if I hit 20ppm ?? When should I add more bleach to "keep it" at 20ppm ??

By testing your water. You DO have a good testkit with the FAS-DPD chlorine test, don't you? It's a BASIC piece of pool equipment!
When should I add more bleach to "keep it" at 20ppm ??
When your testing has shown that the level has dropped below 20 ppm.

Hope this helps. You really need a good test kit, Many people don't get one until they run into a problem like yours. If you has been testing your own water all along... you get the idea.

HI,
I dumped in the 8 gallons of 6% Bleach on Tuesday morning , then had to leave town on an emergency for work so I only got back tonight .I do not have the FAS-DPD chlorine test kit and will get one, however the pool water looks much clearer now , pool test kit shows 2-3 ppm chlorine, Alkalinity of 100, and pH of 6.8, so I added a little pH rise and we"ll see tomorrow eveneing how it is .I think we might have cleared up some of the CC problem.
Can anyone tell me where to get a FAS-DPD chlorine test that goes up to 20ppm?
thanks

the FAS-DPD test will go up to about 50 ppm FC! You want a Taylor K-2006 or the TF100 from TF Test Kits (google TF Test Kits).

Don't forget that Leslie's On-Line sells their FAS-DPD Chlorine Service Test Kit that is a twin to the K-2006, just re-badged for Leslie's. About $60 or $70. Sadly, they no longer have the vast range of single kits--you could buy just a FAS-DPD test or just the reagents from them but it doesn't seem so anymore. I read that Taylortechnologies.com got hacked so C/C purchases on line are closed there. I don't know if it's true.

All 3 kits are equivalent--whichever you get will pay for itself VERY quickly. I bought my PS-232 when I still had a 15'x3' Intex Donut and it STILL was worth its weight in gold to me.

The least expensive source for the Taylor K-2006 I believe is this link while the TF100 kit at tftestkits.com that waterbear talked about is at this link but has 36% more volume of reagents so is comparably priced "per test" to the first link. The Leslie's kit is also sold online here. Of course, you need to add shipping costs to compare what it would be compared to driving to Leslie's, though with gas prices these days just driving around is a factor to consider!

Yes, it's true that Taylor no longer accepts credit cards online since they were hacked, but they do take credit card orders over the phone (during business hours). Another alternative for individual kits, such as the Taylor K-1515-A for just the FAS-DPD chlorine test if you've already got the others, is poolcenter.com here.

Not a worry. I've never seen the FAS-DPD Chlorine Service Test Kit in a store, just online. I once, in one store, in White Plains, NY, found the FAS-DPD powder. The clerk didn't know what it was, how to price it, etc. so he just gave it to me! In the store in Greenbrook NJ, they had the combo FAS-DPD test--not a full kit, just FAS-DPD and Monopersulfate (which uses the FAS-DPD reagents + 1) for $20 so I grabbed it--Taylor sells this one kit for $65!!!!! But that's all.
