I use the frog bromine system and Taylor k-2006 fans-dpd kit in a intex 210gallon inflatable vinyl bubble spa. My FC registered 2.5, CC .5, PH 7.4, Alk 50. At 101 degrees, my wife and I spent 1 hour with bubbles on and the next morning my FC was .5 CC 0., PH 8.0, TA 70. What happened??? First time I have seen my levels change so dramatically. I have added more leasure time sodium Bromide 2oz of it but it did not register on FC. Is Sodium Bromide and frogs Sodium dichlorvos-s-triazinetrione not the same?? Please help, I am a little confused
