Hi Mjones,
If I noticed anything about baq during the years I was on it (yes i could be rich had I switched sooner) is the test numbers are at best unreliable. you could possibly have 51 shock but my guess is you really have none. The shock is hydrogen peroxide and doesn't last long anyway. It also doesa not interfere with the conversion. it ios the baqucil that reacts with the chlorine and turns it green. I wouldn't give another thought to the baq shock. A good test kit tho!!!!!!
