So I've been working on opening up my pool for the summer and cannot seem to get my cyanuric acid under control. I have had a sock filled with this for about 3 weeks now (and from what I read understood I'd see some amount of difference by a week), and my readings continue to stay at 0. What can I do? It'd be nice to get this green nastiness out of there, but I know I need to get this under control first so I know how much bleach to start adding. Could it be the sock I'm using isn't putting enough into the pool? Should it empty out from the sock daily or over several days? The sock seems about the same as when I added to it this past Saturday.
Any help on this would be appreciated.
