I've been pool and spa stored, I tell ya!
Emptied, cleaned and refilled my hot tub. Added a little too much Diclor so to neutralize a bit of the chlorine I added hydrogen peroxide 3%. Worked like a charm. Who knew??
Went to local pool and spa store to get a new filter and realized I hadn't used the Robards pH stabilizer product I normally use on start up (can't recall the exact name but you add a bottle of this on start up to qwell pH drift). The salesman said that since the tub is already hot those products don't work so well when added to hot water, and instead to use an entire 16 oz bottle of Brilliance brand Total Alkalinity Increaser.
Well, I don't know what this is about but now I have pH out the roof and with repeated administration of Muriactic Acid my TA is finally down to 100 and my pH is still 8.2 or greater. Currently my FC is 8 with CC of .5.
