Jared, Joel (JVTrain) and I are concerned that you may have ammonia because you added bleach earlier, then only had 1 FC remaining after 30 minutes. That's a big drop. So tomorrow, go ahead and grab some more bleach, then please perform the following steps to ensure you remove any suspected ammonia and can begin your SLAM:
1. Begin a SLAM by dosing FC up to SLAM level. If your CYA test is showing as zero (perhaps already converted to ammonia), use a SLAM/Shock FC of 10. Do not add additional CYA at this point.
2. Retest FC at 10-minute intervals.
a. If FC loss is greater than 50%, add FC to bring back up to SLAM level and continue retesting FC @ 10-minute intervals.
b. IF FC loss is 50% or less, add FC to bring back up to SLAM level. Go to Step 3.
3. If CYA is below 30 ppm, add enough CYA to bring level up to 30 ppm.
4. Continue SLAM as directed in the SLAM article until the SLAM Criteria of Done are met. Test as directed in the SLAM article - no longer need to test FC at 10 minute increments at this point.
If you perform this 10-min drill correctly, you'll complete a huge hurdle. But make sure you have a good amount of bleach available, or that you can get more quickly if needed. You'll be doing some (pool) babysitting tomorrow morning.
