One of the upsides to high stabilizer is that you don't have to add bleach as frequently. The downside is that, if you let algae get a foothold, it takes a LOT of bleach to get it shocked. I tend to run my stabilizer in the 80-90 range, but I live in Louisiana and my pool is in full sun almost all day. I add bleach every 2-3 days, but I also tend to keep my chlorine on the high side of the recommended range.
