Ok. Pool store didn't have the dpd-fas kit but they had the refills. So I got that, is it the right stuff (R0870 and R0871)? Since I don't have the kit how much powder do I use in the 10 ml sample?
yep thats it.
the powder should come with a little blue plastic scoop....you use one scoop, in 10ml of pool water then count the drops (each one is .5)
try to use 5mL sample for FC test without dilution to keep things simple. It gives 1 ppm resolution.
Ok, we went swimming and everything was fine ...
