I bought a used Aqua Medic twin reef doser off of RC (he said it was 7 months old). I got it on Saturday and didn't have time to set it up until Monday. Well every since then all I've been doing is working with it. I have read the manual over a dozen times and pretty certain I have everything set up right, but I can't seem to keep it primed. I have the check valves setup on the out put side, I have it above the dispensing jugs and below the water level of the aquarium. I don't know what to do, if someone has one of these and can give me advise I'd appriciate it
