Reducing flow makes it quieter but still not great but I have no valve yet can only pinch the hose.

I should note that I did Kevin's 'red coral mod' and simply took out the bottom red plate so water just exits the tube. Maybe that is related to the noise I'm not sure?

WOW, you are not kidding! You have some major flow, so far we are hearing very positive results as to how well these beads tumble because of the size and shape! These Extra Beads are more dense and weigh more in comparison to the larger beads.

I almost guarantee you that the noise you are experiencing is due to removing the bottom plate, the water is pounding the beads against the bottom plastic of your TLF like a drum nstead of rising up through them.

O.C.
