I need some assistance. My FC just dropped from 6.5 PPM TO 0 PPM within 24 hours. There has been no rain, my heater is off, etc The only thing I did was to add a stain remover yesterday morning. Could the stain remover cause such a drop on FC? or could it cause false reading? Please help....I do not know what to do.
