Welcome to our forum.
The shock they gave me is the SPA Essentials Spa shock Xtra. Is this the right stuff, and how much and often do I use it?
wmccall,I used it for 6 months, but since my dealer quit selling spas and my nearest HS dealer is in Stillwater (OSU home), .
2) Typically you put the N2 cartridge inside the filter or the filter standpipe but if that's not feasible many do just place it in the filter basket as long as you can do so without it interfering with the basket's ability to skim.
It comes with a couple extentions so you can keep it high enough so you can get at it.
