FC Off The Chart

[JTAG]

Trying to convert my spa to BBB this weekend but due to a comedy of errors I ended up overshooting FC (off the charts). My Taylor kit ran out of chlorine reagent and I trusted some test strips. I did go and find some reagent and when I tested it was off the charts.

Should I let it come down naturally or should I drain some water?

I was initially using Dichlor to introduce CYA but I'm not sure where I'm at with that now. I will have to do a CYA test when things settle out.

Does it pay to try and balance PH and TA with FC so high?

Thanks for the help Jim

Hot tubs tend to loose about 25% FC per day, so you can figure out from that how long until the FC is back in normal ranges. Usually do not take too long.

Do not adjust ph when the FC is over 10 ppm, it will read high.
