View attachment 797 This is the unit I have and it came with two power heads.The one stoped working while I was in LA. It was making some noise, then the alarm went off and then later on it quite. So I had the Tunzes shut down till I got back a month later.I am hoping to find another pH or two as it can handle 4 ph but this is a old unit and not sure if this model is made anymore. I don't know maybe I can find a used one from somewhere. I haven't tried yet but if I can't will this work.It has the two power heads that I was running on it and I think it was the right one that quite on me. So i was wondering. I have another tunze pump that is just a pump that plugs into the wall. If I have to go this rout can I splice this one on to the end of the one with the controller so I will have two running again. Will this work. If so all I need to do is remove the one and splice the other back on.Can someone tell me if this can or cannot work if this is the way that I have to go.I don't want to just try it and fail. They cost to much to use as ginny pigs.
