That does not address the cause, merely treats the symtom.
To deal with algae, you need to focus on the inducement, the germination, the life history to control and manage it.
You need to see what specifically induces it, not mere correelation of speculation without any real testing.
You will rarely get anywhere without going through that process and be dependent on the symtom treatment from then on, which ususally has a fitness penalty for other non target organisms.
