    Circulating CYA - how long?

    I'm adding some powder CYA (Haviland) and I filled a sock up (no idea the weight actually) and put it in the skimmer and let the pump run all night. About 18 hours later and the sock was empty! The last time I did this, it took a couple of days. I don't know if the work I've done to fix various leaks (suction and pressure side) had anything to do with it, but that sure seemed quick!

    Now, my question is do I need to wait for this to circulate? I have a cartridge filter but seems to me that having gotten through the sock, it's dissolved and should be in the pool and ready for more.

    The CYA may not show up on your test for several days or a week but it's in there. That's why is a good idea to know how much you are adding so you have an idea of where you are in relation to your target number.

    I added mine (9lbs) 3 days ago. It's about done dissolving and my target was 50ppm (154oz). I am currently at 35ppm. Looks like I am on track then. Cool.

    I would give yours a few days and test again.
