I dropped my FC down to 0 before starting. My Ph may have been around 7.6 though. I thought the AA would just pull it down... I did put a sequesterant in actually both before and after because I added water before I started and so I added sequesterant with the water, then treated again after I put in the AA.

So, I'm not sure now other than the Ph. Should I check the Ph and drop it now? Do you think that would make a difference at this stage in the game?

I'm going to order another dose of AA. In any case I'm sure i will have to try again.
