Hi I've been adding CYA (up to 5lbs now) and still can't seem to get it to register even at the 20 level. I'm using solid CYA in a sock in the skimmer. I put this in over a week ago...still nothing. Any other ideas?
Also, just to be sure. One's CYA can also start disappearing if you have a leak. Folks who use autofills and are noticing a trending downward in their CYA can also suspect a leak. The only way to lose CYA aside from a loss over the winter in a closed pool is for it to be splashed out or emptied from the pool either through a leak or down the drain.
