The colder the temp, the more resistance and more voltage to push the amps. To shoot for optimum coating, don't worry about voltage level on the peak but the time of the peak. You want to postpone the peak as long as possible within reason to allow maximum growth. The only time to take concern on the voltage is on a spike or an extremely high peak that would indicate high resistance. ie. burnt connection At 72*, I don't usually go for more than a .5 to.7 mil coating. I've been able to get 1 mil + only by dropping tank temp down to 60* to 64*. This causes voltage to peak a little higher than calculated but not usually more than 2 or 3 volts. In general voltage only varies +-3V max with temp variances on different runs from 60* to 74*. The only problems I've had since I starting using the 720 rule have been due to screw ups in prep. I've dyed 7 different colors so far and no problems with taking good color in about 15 min. Let me know how things go. SS
