I’m not sure where else to put this. I have a pool and have been using bbb for several years now in my pool thanks to this forum.

I also have a spa (morgan) – for years I’ve been using a spa frog (silver chloride 0.5% other undefined ingredients 99.5%) , bromide tablets (1-bromo-3-chloro-5, 5-dimenthylhydantoin 60%, 1,3-dichloro-5, 5- dimenthylhydantoin 27.4%, 1,3-dichloro-5-ethyl-5-methylhydantoin 10.6%) and I add Morgan “shock out” (active ingredient persulfate compound).

I assume I could use bbb for the spa also instead of the above stuff – and use either bleach or chlorinating granules or tri-chlor tablets?
