I have run my CH test several times with the same results. I add the 20 drops of r0010, 5 drops of r0011 and nothing happens the sample stays clear. I have tried it as both regular 25 ml and as a 10 ml test. I even tried it on plain tap water with the same result... Could it be that my r0011 has gone bad? The bottle does not appear stained and is less than a year old and has been stored properly along with the rest of the kit.
We have had a lot of rain and I have not added water in months, the pool is open all year and water is now at 55*
