The Jet Clean is working away! I'll be refilling my tub later today (sorry, Hillbilly -- your advice was good but I'm just way too eager to let it go for 24 hours more. I know the guy I bought it from, so it's not like it's stranger-goo.)
Question: I have two new filters (spa uses two). Do I have to do anything to them before I put them into the spa? I remember someone talking about "purging" a filter.
