Ok....I just checked and both baskets after sitting all night without running and both baskets are completely full. I turn on sheer descent pump and it goes right to set speed. I turn on pump (one we are discussing) for bubblers and bubblers instantly come on but pump ramps up to prime speed. Thoughts? I did reduce prime speed to 2400 and duration down to 10 seconds. As both baskets are completely full after sitting all night would it be safe to disable priming on the pumps? If I do this any chance of damaging pump? I am going to leave lack of prime setting ON.
The only thing I can think that is making this pump go into prime mode and the other not is this one has the heater and filter upstream of it. Sheer descent pump is a straight loop.
