I found the Little Giant PCL-020 that I just bought to be kind of
noisy........unless its running with no restrictions. Just ever so
slightly reduce outflow and it makes noise.........At full flow it was
much to much for a decent effect coming out of the hand pump
aereator......Reduce flow and you had noise........my solution was to
punch a few holes in the plastic tubing that connects the Little Giant
to the hand pump feature and allow some flow to be diverted prior to
getting to the hand pump and noise all but went away.

One thing lead to another though. I used the hole punch thingie that
is commonly used to punch holes in the plastic drip irrigation system
tubing. I inserted a T fitting and attached a piece of the 1/4" low
pressure drip irrigation tubing to the T fitting, and ran it to thr
opposite side of the tub under water, where it discharges. It sets up
a sort of circular flow of water along the tubs perimeter. Adds more
circulation that is not forcefull and dumps some built up pressure on
the pump and eliminated the noise pump had when it had flow reduced
with ball valve. I imagine you could install one of those micro drip
irrigation mister or sprinkler heads and use it as an aereator as
well, or a sort of miniature fountain in a small water garden tub.
