Run the pump for at least 24 hours after all stabilizer has dissolved. Retest in about 48 hours. CYA takes a while to get distributed in the water.

Good point! I would wait a day or so.. When you add dry CYA it normally takes a while to get fully dissolved into the pool water.. I would not think that would be the case when adding water to already dissolved CYA, but do not know that for sure.. As Allen says, it can't hurt to wait a day or so.

Thanks,
