Day 1 of the attack has begun.
The water change brought the CYA down to 70 as hoped. Still higher than ideal, but at least the target and shock numbers are "manageable" for the short term.
We calculated for 17,000 gallons, and whacked the thing with nearly 700 oz of bleach (it had some FC in it from before..long story, that *heh*) which ramped things up into the high 30's or so...which should give him several hours before it approaches the target of 28.
He's committed to testing a MINIMUM of twice a day for as long as it takes, and hopes to have the chance to test 3-4 x a day.
By the time I left (about 2.5 hours after hitting it with the first dose) we could already see the bottom of the pool in the shallow end, so at least he's got something to show for his efforts!
I'm hoping this one goes well, and produces some good results in 3-4 days. It's up to him now!
