Last year I had a terrible time with algae and didn't realize until the end of the season that it was probably mustard algae. I would regular shock our pool with bleach, and a week later it would be green again. I never really got rid of it. My question is, do I need to worry about it this Spring? Should I "super shock" the pool upon opening it? Do I need to wash all the equipment/toys with bleach water now? Does mustard algae die during the winter/storage? Thanks in advance!
