    CYA sock help

    As an alternative to "hold the hanging sock in front of return jet" can I fill the sock then walk around the pool squeezing the sock until all powdered sediments have dispersed from the sock into pool water? i haven't yet found a way or technique as above to secure the sock to the return jet.

    Re: Just had new pool start up

    63john that's a thread hijack, but no, don't sprinkle the powder. Tie a sturdy string around top of sock with a few feet of extra string. Tie it to the end of a 4b2 (2x4) and lay the 4b2 (2x4) on the deck sticking out over the water. You don't want to tie it to the return. The idea is so it hangs in the water a few inches away from the side of the pool, in front of the return. Then squeeze it every once in a while to help it dissolve.

    Re: CYA sock help

    Not sure if it's correct or not, but I put it in a sock and put it in my skimmer. I squeeze it once in while and usually within a day it's dissolved.

    Re: CYA sock help

    I just tied the sock with a small rope running to the handle on a used bleach bottle half filled with water. Set the bleach bottle above one of the skimmers and let the sock hang. The return jet pushes the sock away from the side of the pool so its not resting on anything. Give it some squeezing every once in a while to release all the dissolved CYA.

    Skimmer is easy; just backwash the filter before you do it so you don't have to backwash the filter right after adding the CYA

    Re: CYA sock help

    After my first attempt of adding CYA with a sock hanging in front of a return was a bit of a pain and took longer than I expected, I have moved to the putting it in a knee high stocking with a knot and throwing it in the skimmer basket. Way more water flow there and it's dissolved within 12 hours. Just need to make sure you keep the pump running.
