Thanks to all for the quick responses.
The filters are about the size of a standard paint roller, so I guess 10". I have been buying the carbon version of the 5 micron. I not sure of a simple way to put chlorine in the tank - short of unlacing the cover and schlepping a ladder down there.
I think that the frequency of the vibration is way higher than what I remember to be a water hammer. Ditto the pump cycling on/off very fast. Lacking access to an audio spectrum analyzer these days, I'm going to guess that the frequency of the vibration is about 100 Hz. Folks at the Water Works downtown told me the the Grundfos MQ pump is not intended to be used with a tank.
Going to make a couple of calls; will post resolution.
