Mustard Algae

To permanently get rid of mustard algae, you first SLAM the pool normally, following the directions in How to SLAM Your Pool. Once you have completed SLAMing your pool in the standard way, raise the FC level up to the extra high mustard algae shock level for 24 hours. Use PoolMath, or see the Yel/MstrdShock column in the chart in this post, to find your mustard algae shock level.
