Greetings. Since it seems difficult to distinguish MA from regular green algae, why not recommend routinely doing a 24 hour MA shock at end of any greenish algae SLAM? / BTW, I always wondered how a case of authentic MA passes the OCLT and low CC criteria of the initial SLAM, before one does the 24 hour elevated-FC MA SLAM? I assumed the presence of MA would keep those 2 criteria from passing. Thanks all.
