Okay, so I picked up some stabilizer at work to raise my CYA. Read the bottle that said to either broadcast in the deep end or add directly to the skimmer. So, I broadcast the CYA around the deep end and then prepared all of my gear to vacuum the pool. When I got my trusty pole, hose a vacuum head all hooked up and ready to go I got in the pool to lightly brush the corners of the deep end and noticed all of the CYA sitting on the bottom on my liner. IT was at that moment that I recalled reading something about a mesh sock for adding chemicals like this. Anyway, to shorten this story up a bit, I didn't like the idea of the CYA sitting on the liner while it dissolved so I vacuumed it into the filter. I figured if it was OK to add it to the filter, there is no reason not to vacuum it up and but it there. Anyone see a problem with this? Filter pressure went up about 1psi which I figure is about normal for this.
