Hello! I am new. My cya level is extremely high.
cya=173 Confirmed by pool store and cya strip test. (Pool store uses ClearCare Expert and strips to compare, I don't know if that matter or not.) I know they can be inaccurate, but I really do think it is pretty high. We have gone through two boxes of granular shock from Sam's Club this year with fighting algae, without realizing what that adds. We also put a bunch of pucks in our floater and one in the basket, on top of already having a cya=90. So I think that along with using some granular shock really skyrocketed our cya level.
So, my main question is, if I drain the pool below the basket level and add new water in for a few nights, do you think we can get the cya level lowered? What have you found? We do not have a pump to pump water lower than below the basket level. So, I figure if we do that a few nights, while circulating fresh water in, that we can eventually get the cya level lower? (I am wondering how long this may take, removing and adding, if you have experience.)
Last question, should we stop adding bleach if our FC=14.39 with the cya level what it is? I know the FC should be higher to reach shock level, but with cya so out of hand, it seems like a lost cause to even bother with FC right now. Correct? Once we get the cya level at 50, I plan to slam the pool. I have been adding a jug of bleach a night just to keep the algae some what under control.
I will be buying the full tf100 test next year, too close to the end of season here. I do have the FAS-DPD being shipped. Thanks for any and all help!!
