How do you use this to check your pool chlorine? What else do I need to go with this item to check for chlorine in your pool

I use this with a Hach 1454200 Chlorine (Free and Total) Test Kit, Model CN-70. It is a test kit for drinking water I don't know that it is good for pools. You might want to check out products like: Poolmaster 22260 5-Way Swimming Pool or Spa Water Chemistry Test Kit for your pool. I've not used that product so I do not know how good it is, but at least it is for pools.

Will this work on hanna hi 96711? method: dpd, range 0.00 to 5 ppm?

I have been using them and have not had any problems.

Does this test for chloramine?

I believe you can use the kit to test for "free chlorine" and chlorine. I think there is a formula that uses these values to estimate chloramine levels. I use a RODI system with 2 carbon blocks and have found no chlorine or chloramine in my water.

We have a hach colorimeter that tests free & total chlorine. it's for drinking water. does this reagent work to for both free and total chlorine?

Part number 2105669 is for total chlorine only. The part number for the same size pillows used for free chlorine is 2105569. The procedure is also slightly different for the free and total chlorine tests. You will want to review the method documents for these tests on the specific colorimeter you have to confirm that the tests are being run correctly. Thank you for contacting Hach Technical Support

Needed this quick and got 3 - 100 packs and they all showed up in time for my review

Quick, Fast, and effective service. I needed these as my water DP Tabs were out dated, and i needed a bunch of packets for operations and maintenance of a water system. Made it in great time and was able to get proper readings as the old packets were out dated. So i am happy to have recieved these in the knick of time. I passed my site water safety in a timely manner.
