thanks

If you remove the tube, it should be capped off like I mentioned above so it doesn’t pull water in there as that will reduce the air intake and cause more salt buildup in the venturi port. Leaving it connected allows it to pull air and possibly a bit more than the venturi port alone. Either capped off or connected so it can pull air is best. Also finding the best pump speed is important which for an SM250 will typically be between 36 and 38. In some cases a bit lower or in others as high as 40w. Sometimes less is more though so I would start out low and find the speed that gets the most dense foam.
