My previous bottle of R-0871 has a rounded neck. After running out, I switched to another R-0871 I got from TFTestKits that has a sharp cyclindrical shape. With the new bottle, I find it very hard to control the drops - they start dripping out without even squeezing the bottle and the drop sizes seem much smaller than with the old bottle, and I get ridiculously high chlorine readings (50-100% higher than expected). I pulled out another R-0871 bottle with the rounded neck and got great control over drops, nice big round drops, and readings that match OTO and Leslies store readings.
I'm also having a lot of difficulty with a new R-0012 bottle (purchased last year from TFTK) also giving much smaller drops and 50% higher Calcium readings that expected.
Any known issues with the different bottle types?
