Hey guys and gals, I'm bleaching most of my rocks and have a plan to get rid of the dreaded maidens hair algae. How long do you guys bleach your rocks. The first couple of buckets I did for a day and a half and then set them in the sun. I still see a couple of spots where the maidens hair is still green. The rest of it turned white. They have been sitting out in the sun for a week now. I just need to know for sure that all that crap is dead. What do you think!!!
