I have been maintaining my new to me pool for a month or two now and I am very satisfied and comfortable with the pool thanks to the knowledge I have gained from TFP forum and I thank you all for that knowledge. But I digress.
I find that I only use the R-0870 DPD powder and the R-0871 drops to daily check my chlorine. I never use the the yellow capped R-0003 drops to check my chlorine. Is the DPD test more accurate than the R-0003 test? It certainly is easier for me to read the R-870/R-871 test.
