I got some from Intheswim. Not as sludgy as some of the reviews on the website suggested, but then it sat out in 100 degree heat all morning before I finally won the game "Find where in your yard UPS has hidden your packages this time".
My CYA test down around 20 this morning, and I am burning through the bleach with the 100 degree heat and intense sun, so it is time to add more stabilizer. It dissolved well enough by dribbling slowly in front of the return. A few little bits had to be brushed up. The product apparently has a "salt-friendly" pH, whatever that is, so I may have to make some adjustments. My pH and TA have risen some in the last couple weeks- the pH I know is from aerating to cool the pool, not so sure about the reason for the TA.
