Will non-chlorine kill nostoc algae on driveway?

Non-chlorine products, such as oxygen bleach or vinegar, can be effective at killing nostoc algae, although they may not work as quickly or as thoroughly as chlorine bleach. Non-chlorine solutions can disrupt the cellular structure of nostoc, leading to its death. However, the effectiveness will depend on the concentration and application method. A more concentrated bleach or targeted algae treatment might be more effective for severe infestations of nostoc on a driveway.
