What chlorine level to shock -- now that half my CYA is gone

[JimK]

.....
OK. Do this:

1. Use borax to push your pH to 7.8 or so.
2. Tomorrow PM late, add (10) gallons of plain bleach.
3. Test with OTO & phenol red in the AM. Add borax as needed to maintain the 7.6+ pH. Remember that phenol red will not return accurate results if the chlorine is very high.
4. Repeat this cycle till you can sustain a strong chlorine reading overnight.
5. At that point, you should resume using the K2006 testing.

Ok...here we go...did my homework for today.

Added borax this morning to raise pH
Per post above, added some bleach to carry it through the day since this morning's test showed 0 CL
Added 10 jugs of bleach about 8:30pm.

I'll give it about 1/2hr to mix then test to see if any CL shows up this time. I'll get up early tomorrow and test again.

Here's hoping.......

EDIT: Just checked CL using the OTO kit; sample turned dark orange....a good sign! We'll see what it looks like in the morning. Keep your fingers crossed.......
