Notice no claims of algicide by Seachem. Though, from the above
comments, it's not unreasonable to infer that perhaps Excel is at
some level an algicide, but Seachem is not willing, or not allowed, to
make sucha a claim. You are the one who, on anectdotal evidence,
claims absolutely that Excel is not an algicide and is in fact good to
grow algae with.
all that says is that "algae can't feed on it". It is a far leap to say
that means that it kills algae or that it is an algicide.
Snippets of email from Dr. Greg Morin, CEO of SeaChem:
There are products which claim to kill algae but I didn't know they
might have to meet any EPA qualifications.
Yes, they do. They _should_ have an EPA registration # on them. If not,
they are "illegal" products if they are also claiming to kill algae.
Remember, it is only the claim that counts as far as EPA is concerned.
I can't endorse or discuss your product in any event but it certainly
has me puzzled now. If there were a product that really was effective
for algae but didn't harm plants or invertebrates, I would certainly be
interested in it if there were a scientific study of some sort. AFAIK
SeaChem has a very high reputation.
We would need to do that for EPA registration to make that claim, but
the costs of doing that and the registration/application process far
outweigh whatever we would hope to make off such a product. The
government sets the financial burden so high it is just not worth it ...
I *think* a scientific study of a specific chemical compound could
investigate certain effects upon various organisms without contravening
any product marketing regulations, however I am not an expert on these
matters. Further, we could discuss those findings on public forums
couldn't we? A product containing that compound could then reference
the
study or people could endorse the product citing the study... I am very
puzzled!
A 3rd party would have to do such a study and even then we could not
disclose any findings showing algacidal activity... the 3rd party
could and others could discuss it... but we could not ... yes it is
crazy but that's how it is unfortunately. We could do it but since we
could not disclose anything it kind of defeats the purpose of doing
it.

Later that same day:
I realize there are governmetn regulations concerning what you
can and cannot say about stuff.
I maintain a culture of cladophora algae ("moss rocks"). It
would be good to know if Flourish Excel is harmfull to
them at regualr ot higher dosage. Ie, a warning would be handy.
To answer your question, algae will not fare too well when Flourish
Excel is dosed as recommended. Yes, a warning is probably a good idea.
It had not been thought of to date as typically algae is not desired in
a planted aquarium.

So is Excel an algicide? Certainly not. Have people found
it inhibis algae growth? Most have.
Have you tried seevral large water changes? How often do you change
water in this problem tank?
