Thanks guys!
Bill D. that's helpful to know. I think I'll do just that for a few or three days

. And more rain is expected tonight!
Shorty, I have no aquatic vegetation but it's a good possibility on the algae bloom.
And maybe doing this will also answer the question if my system is what's causing the turbid water to begin with. I had thought it was the oversized GC with nothing to eat stirring it up.
So if no one sees any harm in shutting down for a few/several days, I'll see what happens.
