I just did this a few weeks ago. The price didn't move much over the last several months.Awesome, I'll give it a go myself. Yes, the chlorine feeder is a stand alone unit with no electric component to it.
In your guys experience should I wait til after the fall to purchase the SWG? Do they drop in price during the off-season much? I already have enough chlorine tabs for the rest of the summer, CYA in my pool is at 50 so I figured finishing off this pool season with chlorine tabs will bring my CYA to where it needs to be for salt and possibly get a good deal on the swg.
