I bought a pint of each of the two calibration fluids for under $5 a piece at a local biological/chemistry supply store. This will last for years! My probe was barely drifting for the first 8 months, but then the unit (not the probe) went bad. The meter going bad is rare. Nevertheless, "That Fish Place" replaced the entire unit (new probe included) at no charge! I didn't even have to pay for any shipping. The unit comes with a one year guarantee and the mail order place readily handled it. --Randy ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
