Not defending the use of antibiotics in bottom paint, but nearly all
antifouling is toxic to marine life (which is why it’s used as antifouling ...)
Copper is nasty stuff to marine life and to people (in sufficient doses),
which is why the smart sailor wears a respirator and plenty of protective
clothing when sanding and painting the bottom. Trinidad Pro, until recently,
had an effective (read nasty) pesticide called Irgarol that ran into trouble
with the EPA.
Those of us who are older may remember tin-based bottom paint that worked
wonderfully, but created aquatic dead zones around your boat.
Using antibiotics unnecessarily is bad (both in farming and sailing) because
bacteria adapt quickly and can learn to outwit particular types, making those
antibiotics ineffective.
Just saying ... none us us has cleans hands in this. If you have a sailboat,
you’re harming the environment to some degree.

Anybody dumping Roundup in to their bottom paint and the waters in which we
sail should be taken out to the barn and shot. Dumping a witches brew of anti
biotics into these same waters is similarly ignorant IMO. Complain about the
EPA all you like, but someone needs to take on the unenviable task of
protecting the rest of us and our sailing waters from the ill informed and
questionably intentioned. My 2 cents.

You want the stuff to perform as designed.. You apply it as prescribed. If
the tetracycline was as effective as claimed, it would be in the paint from the
factory.
BTW, My burnished Trinidad Pro is still pristine (I check it regularly when
we swim) after being constantly in the water 1.5 years. It's not real long yet
but that is 1.5 years continuous. My competition scrubs their VC-17 bottom
every week, I scrub it never yet we're fast enough to consistently show-up on
the podium despite our inexperienced team's frequent mistakes and my old
bedsheet sails. :-)

I think any drug like " tetracycline" will kill lots of germs and bacteria
but will dissolve so fast in water, it will be gone in a few days. I wouldn't
add anything to bottom paint for fear of jeopardizing the adhesion and slow
release of it's own toxins. I've heard of people mixing in "Round Up" and I've
heard the same people complain that their paint flaked off during haulout. I
ask them if they sanded with 80 grit paper before painting as directed, and can
tell by their confused expression, they never read the directions.
I respect the guys who write the application instructions, follow those as
close as I can and I've enjoyed great success.
I understand your frustration with VC-17. I used VC-Offshore for 8 years and
got fed up with the fouling. Had to clean the bottom each week to stay ahead of
it. Used a piece of carpet and sometimes a 3M pad. Switched to a better paint,
Micron 66, and love it. Kept the boat in all winter and the fouling looked
pretty bad this May. All the boats in y marina had a fur attached to their
hulls. I was surprised how easy it came off easily with a soft deck brush, and
very little pressure. Micron 66 is designed for Salt Water and Fresh Water
requires "Micron Extra" I think. Both can be burnished, but the paint goes on
very smooth as is, and by design gets smoother as it ablates. They are multi
season hard abatives.
