Good morning all. Thank you for clarifying that once the sample goes clear, that’s the true reading. At 09:30 EST I tested the water and it came back at 2 ppm. I have the speed stir with the light and will be using that moving forward.. At 0935 EST I put three more gallons of liquid chlorine in the pool. At 10:17 EST I tested and it took 6 drops of the R-0871 to give a 3 ppm reading. At 10:28 EST I put 3 more gallons of liquid chlorine in. 10:56 am EST the test showed a drop to 2 ppm. At 11:02 am EST I put 3 more gallons of liquid chlorine in the 20,000 gallon vinyl lined pool.At 11:42am EST I tested and got a 4 ppm result with 8 drops of R- 0871. It’s starting to get some sun coming through the clouds. I’m not positive but it seems like I have put in about 15 gallons of liquid chlorine into the pool since yesterday. I’m attaching the photo I just took around 11:45 am EST. It appears the pool is lightening up some. My understanding is that I can’t put the CYA in until my readings are at least 6 ppm or more and holding for at least 10 minutes. I do have a concern that all this chlorine is going to bleach the vinyl liner. Should I keep putting liquid chlorine in until the ppm gets up to 6? I’m only focusing on the FC right now is that correct? Sorry but I believe I need a little more guidance if possible thank you.
