Keep in mind Excel is an algicide.




Not really. In fact, algae grows quite well with excel, it seems to like
it.


Yeah, really.

You must have way more algae than it can handle then. If you write to Greg,
CEO of Sea-Chem and ask him if it's safe to grow Cladophoa he'll tell
you no, it'll kill it. But US Government regulations prevent him from
claiming it's an algicide.

It may not be a great algicide but the acetyl compound in it that releases
carbon is death on algae. (Even acetic acid kills algae in small doses).
