Here is our Frankenstein setup we have been using the past month. A Unger radius brush & a DA Components bronze wool attachment with a Tucker swivel on a Gardnier goose neck.
Been really happy with this setup, we really like the radius brush. The flared lip on the brush is ideal for sills.
I have one. It is perfect for easy access and very light weight and has a great handle and base to store and unload. Changing the Resin is much easier also.
We currently are using the hydro but it’s too expensive. Our tds is above 200 so I recently ordered a multi filter system. If you are using your WFP daily and have tds above 100 it’d be cost effective to use a multi filter system
