Janie, what are the ohms in the cartos you're using in the tanks? Are they the same cartos you use not in tanks? If they are the same cartos, I'm going to go out on a limb and say you're not getting the cartos wet enough. You siad you pre-fill and wait 20 minutes but maybe you're not pre-filling enough? If they are different cartos, let us know what omhs you have. We should be able to help you figure out if they'll work on your riva or not. There is no reason they shouldn't if you have the right cartos. There isn't anything about a tank system that would preclude use on any
PV as long as the
PV can drive the carto.
