I have been slamming my pool for the last 4 days. Every morning the pool looks clear but then after i brush the bottom I can clearly see something like dirt / algae being stirred up and then it makes the water cloudy again. 1.) Is this algae? 2.) Based on the SLAM process, if your pool passes the overnight chlorine loss test, does this guarantee there is no more algae regardless of whatever i'm stirring up?
