I just started using the BBB method of pool maintenance about 8 weeks ago. The cell on my salt system quit working and I decided to give this a try. The pool has looked perfect from day one and it has been simple to maintain the chemical levels, but last evening I noticed some brown spots appearing on the liner. I read some of the posts on algae and I am a little confused about killing it with a high level of stabilizer in the pool. My level has been at about 95 ppm since early in the season since I added 10 lbs. of cyanuric acid instead of alkalinity increaser. If anyone has any suggestions I would welcome the help. I have a 24,000 gallon pool with a vinyl liner. My pump runs 24 hours a day and I have a Pentair DE filter.

Your site is great. I always suspected you did not have to use chemicals from a pool store and the poolforum was the first place that showed me how to avoid them.
