I am right now researching either of these, to convert from Trichlor pucks. I was initially planning to go with a Stenner 45MHP10 for bleach, but now am also considering the move to SWG. Overall initial cost will higher with SWG, but I am also looking for ease of maintenance for the long term. In any case, I will be moving to some sort of automation as I cannot see me fooling with jugs of bleach every day. I honestly haven't done much research in the way of SWG, so don't yet even really know what else comes along with doing SWG. I understand you have to add salt, but how do you go about that? TIA.
